Chemical Name: 1-Naphthyl Phosphate
Common Synonyms: 1-Naphthylphosphoric acid, Naphthalene phosphoric acid
Appearance: White or off-white powder, may clump
Odor: No distinctive smell
Common Uses: Analytical chemistry, enzyme substrate in diagnostic kits, biochemical reagent
CAS Number: 113-06-4
Main Hazards: May cause eye and skin irritation, respiratory tract irritation when dust forms, potential for minor inhalation risks, not considered acutely toxic in small laboratory amounts
Risk Phrases: Irritating to eyes, respiratory system, and skin
Environmental Warning: Harmful to aquatic life in large spills, runoff concerns in poorly contained settings
Principal Ingredient: 1-Naphthyl Phosphate, often at purity higher than 95%
Impurities: Trace organic and inorganic residues possible depending on synthesis but rarely above 2% in analytical grade samples
If Inhaled: Move to fresh air, monitor for persistent coughing, rinse mouth and nasal passages with water
If Skin Contact Occurs: Wash thoroughly with water and soap, remove contaminated clothing
If Eye Contact Happens: Rinse with water for several minutes, blink frequently, seek medical care if redness persists
If Swallowed: Rinse mouth, avoid inducing vomiting, consult a medical professional if discomfort continues
Suitable Extinguishing Media: Water spray, dry chemical, carbon dioxide
Hazards from Combustion: Produces carbon oxides and phosphorus oxides, possible irritating fumes in a fire
Protective Equipment: Use of self-contained breathing apparatus, full protective clothing recommended for responders
Special Advice: Avoid breathing dust and fumes, evacuate area in case of large fire, restrict access to authorized personnel
Personal Precautions: Avoid inhaling dust, ventilate area, use gloves and goggles
Spill Control: Collect spilt material with damp cloth or absorbent, avoid dispersing dust in air
Environmental Precautions: Prevent entry to waterways, clean up thoroughly to limit environmental exposure
Clean-Up Methods: Sweep or scoop into sealed containers, wash residue away with plenty of water
Safe Handling: Minimize dust production, use in well-ventilated areas, avoid contact with eyes and skin
Storage Requirements: Store in tightly sealed containers, keep cool and dry, separate from incompatible substances such as strong oxidizers
Incompatibilities: Avoid strong acids, bases, and oxidizing agents to keep chemical stability
Typical Container: Non-reactive plastic or glass with desiccant when long storage is needed
Ventilation: Local exhaust or fume hood whenever possible
Personal Protective Equipment: Safety goggles, gloves made of nitrile or PVC, lab coat
Respiratory Protection: Dust mask or particle respirator for bulk handling
Hygiene Measures: Wash hands after handling, do not eat or drink in work area, keep work surfaces clean
Physical State: Solid powder
Color: White to off-white
Odor: No pronounced smell
Solubility: Moderately soluble in water, limited in organic solvents
Melting Point: Decomposition before melting
pH (aqueous solution): Mildly acidic
Vapor Pressure: Not significant at room temperature
Reactivity: Stable under normal lab storage conditions
Chemical Stability: Stable in dry, cool conditions
Conditions to Avoid: Exposure to moisture, high heat, incompatible materials may accelerate degradation
Decomposition Products: Produces naphthol, phosphoric acid, carbon oxides at very high temperatures
Reactivity Alerts: Keep away from strong oxidizing agents and acids to reduce risk of hazardous reactions
Routes of Exposure: Inhalation, skin and eye contact, ingestion through accidental mishandling
Acute Effects: Mild to moderate irritation possible for eyes and mucous membranes, burning sensation upon repeated skin exposure
Chronic Effects: No clear evidence in literature of carcinogenicity or chronic toxicity in standard laboratory handling
Sensitization: Rare, but sensitive individuals may experience allergic reactions with repeated exposure
LD50 Data: High, suggesting relatively low acute toxicity
Behavior in Environment: Tends to persist in soils and water, may degrade slowly, large amounts could harm aquatic organisms
Bioaccumulation: Not likely to bioaccumulate based on molecular structure
Toxicity to Organisms: Low to moderate at realistic concentrations for most aquatic invertebrates and fish
Mobility: Soluble fraction can move in water, avoid runoff into natural streams or sewage
Disposal Method: Collect and send excess or waste to licensed chemical disposal company, avoid drain disposal to limit aquatic contamination
Packaging: Ensure containers are sealed, labelled, and resistant to breakage
Recycling or Reuse: Not common, best practice is incineration or controlled landfill as chemical residue
Global Transport Status: Not listed as hazardous for most land, sea, or air transportation under common regulations
Packaging Recommendations: Use robust containers to prevent breakage and leakage, powdered form should be doubly contained
Labelling: Indicate chemical name and hazard class clearly on all shipments for international customs
International Chemical Inventories: Registered in most countries for laboratory and research use
Occupational Exposure Limits: Not specifically set in major regulatory frameworks, standard lab hygiene rules apply
Reporting Thresholds: Not listed as a priority pollutant under common environmental statutes
