Chemical Formula: K2HPO4
CAS Number: 7758-11-4
Recommended Use: Buffering agent, fertilizer ingredient, food additive, laboratory reagent
Supplier Details: Manufacturer/distributor contact info needed for full traceability in inventory, ensure direct communication for rapid inquiry response
Emergency Phone: Provided by distributor or local governing agency for immediate incident handling
Classification: Low hazard for health under normal usage, but can be an irritant
GHS Label Elements: No pictogram mandated under typical handling, may display exclamation if concern exists for local irritation
Signal Word: Warning
Hazard Statements: May cause mild skin and eye irritation, can be harmful in large quantities or with prolonged exposure, slight slip risk if spilt
Precautionary Statements: Hold container securely, avoid contact with skin, eyes, and clothing, ventilate area, utilize basic dust controls
Potential Health Effects: Minor respiratory tract irritation on inhalation, stomach upset on accidental ingestion, rashes if left on skin, eye redness or pain if directly splashed
Chronic Exposure: Unlikely to cause long-term health effects at standard exposure levels, occupational users advised to follow existing site protocols for dust and skin
Chemical Name: Dipotassium hydrogen phosphate
Concentration: Typically above 98% pure in reagent and technical grade sources
Impurities: Trace amounts of potassium chloride, sodium salts, process water, and other phosphates depending on manufacturer
Product Form: Granules, crystalline powder, or solution—formulation details guide site storage and handling
Inhalation: Move exposed person to fresh air, monitor for persistent coughing or breathing difficulty, consult healthcare if symptoms do not subside rapidly
Eye Contact: Rinse eyes gently with clean water for at least 15 minutes using eyelid control, remove contact lenses if present and easy to do, seek medical attention for discomfort
Skin Contact: Remove contaminated clothing, wash affected skin thoroughly with soap and water, persistent redness or irritation requires medical advice
Ingestion: Rinse mouth out, offer small amounts of water to dilute, do not induce vomiting, call a poison center for recommendations, stay calm and observe for symptoms
Symptom Note: No specific antidote, symptomatic and supportive care dominates field response
Flammability: Non-combustible, product itself does not support fire
Explosion Risk: No risk anticipated in typical use, dust clouds may rarely present a minor ignition source in extreme cases
Suitable Extinguishing Media: Water spray, foam, dry chemical, carbon dioxide—pick based on surroundings, product will not react dangerously with water
Special Hazards: Thermal decomposition or intense heat can liberate irritating phosphorus oxides, mass decomposition requires respiratory protection
Firefighters Advice: Use positive pressure, self-contained breathing apparatus, full protective clothing, avoid smoke inhalation and surface runoff
Personal Protection: Wear gloves, close-fitting goggles, dust mask if local concentrations high, boot covers for large spills
Spill Handling: Sweep up solid material or vacuum using HEPA filter equipment, avoid creating dust, wash area with plenty of water
Environmental Precautions: Prevent entry to drains, waterways, or soil, collect residues and place in appropriate waste containers for managed disposal
Cleanup: Isolated small spills may be cleaned with damp absorbent material, double bag and label all residues for full transparency, keep workplace records for regulatory compliance
Handling: Avoid dust generation, decant from containers slowly to minimize agitation, ensure good ventilation, cease use and consult if powder clouds form
Storage: Store in tightly closed containers, cool and dry area, segregated from acids and oxidizers, avoid direct sunlight or humidity to preserve product stability
Special requirements: Access control in bulk storage, routine inspection for clumping or caking, ensure material is appropriately labeled and inventoried
Occupational Exposure Limits: No established OSHA, ACGIH, or NIOSH limits, control implemented through best practices and workplace air monitoring if heavy use
Engineering Controls: Local exhaust ventilation, keep transfer points contained, high-efficiency particulate air (HEPA) filters when vacuuming
Personal Protective Equipment: Safety glasses or chemical splash goggles, light but durable nitrile or latex gloves, lab coat or long sleeves, respirator for dusty conditions—personal comfort plus site protocols guide final choice
Hygiene Measures: Wash hands after handling, avoid eating or drinking in reagent areas, remove and clean contaminated clothing separately
Appearance: White, crystalline solid or fine powder
Odor: Odorless
pH: 8.8 to 9.6 (1% solution in water)
Melting Point: Decomposes above 204°C, does not melt cleanly
Solubility: Highly soluble in water, insoluble in ethanol
Boiling Point: Not applicable, decomposes when heated
Vapor Pressure: Negligible at standard temperatures
Density: Approximately 2.44 g/cm3 at 20°C
Other Features: Non-volatile, unchanged stability under recommended use, non-flammable
Chemical Stability: Stable under normal storage and handling conditions
Incompatibility: Strong acids, strong oxidizers, exposure to moisture or acids liberates phosphoric acid fumes
Hazardous Decomposition Products: Irritating phosphorus oxides and potassium oxides if heated extensively
Polymerization: Will not occur
Conditions to Avoid: Excessive humidity, high temperatures, open flame contact
Acute Toxicity: Low toxicity for humans, LD50 (oral, rat) >5,100 mg/kg
Skin Contact: Minor irritation may develop with prolonged contact
Eye Contact: Dust or splashes can provoke transient irritation
Inhalation: Dust inhalation may irritate upper respiratory tract
Ingestion: In high amounts, may cause digestive upset; industrial users rarely experience symptoms under normal control
Long-Term Exposure: No evidence of carcinogenic, mutagenic, or reproductive type effects in peer-reviewed literature or official hazard databases
Environmental Fate: Readily dissociates in water, contributes potassium and phosphate to local environments
Aquatic Toxicity: Low toxicity for aquatic organisms at likely environmental concentrations, excess phosphate can promote eutrophication and algae blooms
Soil Mobility: High—phosphate component can leach to groundwater if waste improperly managed
Persistence/Degradability: Rapidly dissociates, does not bioaccumulate
Precaution: Strict control over discharge and runoff prevents local water body enrichment, responsible users manage rinses and washings with care
Waste Disposal Methods: Collect all unused material, residues, and incompatible wastes for landfill or hazardous waste collection as per local authority recommendations
Container Disposal: Rinse and recycle if permitted, otherwise puncture and dispose with standard resinous chemical waste streams
Precautions: Do not discharge untreated into sewer or natural watercourses, label all waste for accurate manifesting and record keeping
Industrial Waste Generators: Register with local authority if generating above threshold amounts, consider third-party waste contractors for large or regular batches
UN Number: Not regulated as a dangerous good under major transport standards
Shipping Name: Dipotassium hydrogen phosphate
Transport Hazard Class: Non-dangerous
Packing Group: Not applicable
Environmental Hazards: Not marine pollutant
Special Transport Requirements: Avoid packaging damage, protect from rain and external moisture, maintain integrity of labels and seals throughout transit
International Inventories: Listed on US TSCA, EINECS/ELINCS, Canada DSL/NDSL, Australia AICS, Japan ENCS, China IECSC
Regulatory Status: Not controlled as a hazardous chemical under OSHA, EU REACH, or GHS for its intended uses
Labeling Requirements: Product identifier, supplier contact, recommended use and precaution, specialized emergency procedures clear and legible
Other: Monitor for changes in local, state, or federal regulations since chemical policies can evolve with new environmental findings or workplace health data
