Chemical Name: D(-)-3-Phosphoglyceric Acid Disodium Salt
Synonyms: Disodium 3-phosphoglycerate
Chemical Formula: C3H7Na2O7P
Appearance: White powder or crystalline solid, absorbs moisture from air
Molecular Weight: 228.04 g/mol
Relevant Use: Common in biochemistry labs, enzyme studies, glycolytic pathway research
Primary Hazards: Not classified as highly hazardous, but not completely harmless either
Possible Health Effects: Skin or eye contact can cause mild irritation, dust can irritate respiratory tract, ingestion is unlikely to create toxicity at small amounts though caution is always wise
Environmental Hazards: Low risk, but large amounts contribute to localized pH shifts in aquatic systems
Physical Hazards: Not flammable, not known to be explosive, forms fine dust if handled carelessly
Active Ingredient: D(-)-3-Phosphoglyceric Acid Disodium Salt, purity commonly above 95% in lab usage
Other Constituents: Trace moisture, sodium chloride, possible inorganic phosphates below reporting threshold
Inhalation: Get fresh air, rinse nose or throat if needed, consult a doctor if coughing persists
Skin Contact: Wash area thoroughly with soap and water, seek attention if rash appears
Eye Contact: Rinse with water for several minutes, eyelids open, remove contacts if possible, keep flushing until irritation stops
Ingestion: Rinse mouth, drink water, seek medical help if feeling unwell or swallowing large amounts
Suitable Extinguishing Media: Water spray, dry chemical, carbon dioxide, or foam tackle minor fires
Special Hazards: Not prone to burning, but smoke may include sodium oxides or phosphoric acids
Protective Equipment: Firefighters use basic breathing apparatus to avoid inhaling combustion products
Personal Precautions: Grab gloves, maybe goggles, protect skin and eyes from dust
Cleanup Methods: Sweep up gently, avoid raising dust, choose a dedicated disposable cloth, dispose with regular chemical waste
Environmental Precautions: Keep powder from drains, avoid washing large amount into soil or surface water
Safe Handling: Use fume hood or work in well-ventilated space, don’t eat or drink around the powder, stay alert for spills
Storage Tips: Store in tightly closed containers, cool and dry location, shield from direct sunlight and fluctuating humidity
Incompatibilities: Avoid contact with strong acids, strong bases, and powerful oxidizing agents
Engineering Controls: Work with it in a ventilated area, use local exhaust if transferring lots of powder
Eye Protection: Safety goggles with side-shields
Skin Protection: Nitrile gloves work well, good lab coat helps
Respiratory Protection: Dust mask advised for high-concentration powder handling
General Hygiene: Wash hands before meals, after lab work, never touch eyes or face with dirty gloves
Physical State: Solid, usually white
Odor: Odorless
pH: Neutral to slightly basic in solution
Melting Point: Decomposes without melting at high temperature
Solubility: Readily soluble in water
Stability in air: Stable under typical lab conditions, but hydrates and clumps up if stored in open air
Vapor Pressure: Not volatile
Chemical Stability: Stable in dry air and neutral water, breaks down in strong acid or base
Reactivity: Reacts with strong acids, strong oxidizers, may release phosphoric acid if heated with water
Hazardous Decomposition: Phosphates, oxides of sodium, minor organic fragments evolve if burnt
Acute Effects: Mild respiratory, skin, or eye irritation, especially in powder form
Chronic Effects: No strong evidence for long-term harm in typical laboratory users
Toxicity Data: Oral, dermal, and inhalative toxicity reported as very low
Symptoms of Overexposure: Sneezing, coughing, watery eyes, mild stomach upset if ingested
Aquatic Effects: Phosphates may contribute to local nutrient loading, risk to aquatic life only if bulk release occurs
Biodegradability: Organic part of the molecule eventually breaks down, sodium salts disperse in soil
Environmental Persistence: Not persistent, not bioaccumulating
Preferred Method: Small-scale waste mixes into water, goes down drain with ample flushing, still better to collect for chemical waste stream
Regulatory Disposal: Regulations suggest collecting for landfill or chemical incineration, not open dumping, no disposal with food or municipal solid waste
Class: Not dangerous for transport under global regulations
Labeling: No special hazard labeling required, packaging should be powder-tight, avoid breakage or spillage
Precautions: Keep container sealed and upright, don’t ship with acids or oxidizers
Lab Safety Standards: Recognized under standard laboratory chemical protocols
Workplace Rules: Must meet OSHA, EU-REACH, or local chemical handling rules depending on where used
Environmental Discharge: Discharge to water or soil discouraged in large amounts, primarily due to phosphate
Employee Protection: Training needed for safe powder handling, lab safety certification advised
