Chemical Name: Thiamine Monophosphate Chloride
Synonyms: Vitamin B1 Monophosphate, TMP Chloride
Chemical Formula: C12H18ClN4O4PS
Molecular Weight: Around 400 g/mol
Appearance: White to off-white powder with no distinct odor
Uses: Nutritional supplements, food fortification, laboratory reagents
Main Hazards: Irritation to eyes, respiratory tract, and skin can occur after contact with large amounts of Thiamine Monophosphate Chloride. Inhalation of dust can trigger coughing, sneezing, and mild headaches. Prolonged contact sometimes causes mild skin redness.
Routes of Exposure: Inhalation, eye contact, skin contact, ingestion
Regulatory Classification: Generally considered of low acute toxicity, but handling large quantities demands care.
Active Ingredient: Thiamine Monophosphate Chloride
Chemical Concentration: Usually provided as a pure compound for industrial or laboratory use
Impurities: Negligible, batch-specific information can sometimes reveal small traces of related thiamine compounds
Eye Contact: Rinse eyes under running water for several minutes. Remove contact lenses if present. Seek medical help if irritation doesn’t subside.
Skin Contact: Wash area thoroughly with soap and water. Remove contaminated clothing. Persistent irritation warrants medical consultation.
Inhalation: Relocate person to fresh air. Help them breathe calmly. If coughing or discomfort continues, speak to a healthcare provider.
Ingestion: Rinse mouth with plenty of water, avoid inducing vomiting, consult a health professional right away for larger amounts.
Suitable Extinguishing Media: Water spray, dry powder, foam, or carbon dioxide all put out small fires involving this compound.
Hazardous Combustion Products: Burning produces carbon oxides, nitrogen oxides, and hydrogen chloride. Keep firefighters upwind, provide self-contained breathing apparatus.
Advice for Firefighters: Firefighters should wear protective clothing and avoid inhaling dust or combustion fumes.
Personal Precautions: Avoid breathing dust, ventilate area well, prevent skin and eye contact.
Environmental Precautions: Prevent large spills from entering drains or watercourses.
Spill Cleanup: Shovel or sweep up powder, bag securely and dispose of according to local waste disposal rules. Wet wipe surfaces to minimize dust.
Handling: Use gloves, goggles, and dust masks to reduce risk. Work in well-ventilated areas. Keep handling containers closed when not in use. Avoid generating airborne dust.
Storage: Store in tightly sealed containers kept in cool, dry, and well-ventilated locations. Protect from direct sunlight, heat sources, and moisture.
Exposure Limits: No specific regulatory exposure limits for Thiamine Monophosphate Chloride, but general dust limits can provide guidance.
Ventilation: Use local exhaust or general ventilation to control dust. Fume hoods in lab settings reduce risk.
Personal Protective Equipment: Safety goggles, chemical-resistant gloves, lab coats, and N95 dust masks keep users protected during handling.
Physical State: Crystalline powder
Color: White to off-white
Odor: Nearly odorless
Solubility: Readily soluble in water, forming clear solutions
Boiling Point: Not applicable under standard use
Melting Point: Decomposes before melting
pH (aqueous solution): Slightly acidic to neutral
Chemical Stability: Thiamine Monophosphate Chloride stays stable under recommended storage conditions. Exposure to strong acids, bases, or oxidizers can break down the compound.
Hazardous Reactions: Avoid contact with oxidizing agents or strong bases.
Decomposition Products: Breakdown may generate irritating or toxic vapors such as oxides of nitrogen, carbon, and hydrogen chloride.
Acute Toxicity: Low toxicity in small, expected doses. Large ingestions could cause gastrointestinal upset.
Chronic Effects: No clear evidence of long-term toxicity in people exposed during normal handling.
Irritation: Proven mild eye and skin irritation at high concentrations.
Sensitization: No well-documented cases of allergic response under routine exposure.
Mutagenicity / Carcinogenicity: No evidence points to cancer risk or genetic mutation under practical conditions of use.
Ecotoxicity: Thiamine Monophosphate Chloride doesn’t persist or bioaccumulate under standard environmental conditions. Large spills may momentarily affect aquatic microorganisms, but wide environmental impacts seem unlikely.
Biodegradability: Expected to break down fairly quickly through natural processes.
Mobility in Soil: Soluble form means it can readily move into water with runoff, although dilution typically prevents harmful effects.
Waste handling: Dispose of excess or expired product through authorized waste collection or hazardous chemical disposal services.
Environmental Precautions: Keep significant amounts away from surface water. Do not dispose by flushing into sewers.
Regulations: Follow national and local guidelines for non-hazardous chemical waste.
UN Number: Not classified as dangerous for transport
Transport Hazard Class: No specific hazard classification under most international transit standards
Packing Group: Stable under normal transport. Avoid contact with water during shipment. Use leak-proof, sealed containers.
Global Inventory Listing: Thiamine Monophosphate Chloride appears on several chemical inventories including those in the United States, Europe, and Asia.
Occupational Safety Laws: No unique requirements specified by most health authorities beyond standard chemical hygiene.
Food Use Approvals: Many countries allow this compound as a vitamin supplement basis, subject to purity and labeling.
