Name: Trigonelline Hydrochloride
Chemical Formula: C7H8NO2·HCl
Common Uses: Frequent presence in research labs exploring plant alkaloids, analysis of coffee biochemistry, pharmaceutical studies
Appearance: White to off-white crystalline powder
Odor: Typically lacks a strong smell
Solubility: Dissolves in water rapidly, forming a clear solution
Other Physical Forms: Sometimes observed as granules, but always dry and free-flowing in pure samples
Main Risks: Dust generation during handling can cause mild irritation to eyes, skin, and respiratory tract
Health Effects: Direct contact or inhalation leads to redness or coughing but not considered acutely toxic at low doses
Regulatory Status: Not listed as a carcinogen by recognized health authorities
Risk Phrases: Physical harm is low unless in large uncontrolled quantities or fine airborne powder
Reactivity Risks: Stable in normal storage and handling but can create slip hazards if spilled
Main Ingredient: Trigonelline Hydrochloride, purity commonly above 98% in laboratory stocks
Impurities: Naturally occurring impurities include minor quantities of related alkaloids or residual solvents from synthesis, rarely higher than 2%
Additives: Generally does not include stabilizers or fillers unless clearly marked by supplier
Inhalation: Move to fresh air, relax and breathe normally; persistent discomfort encourages seeking medical advice
Skin Contact: Remove contaminated clothing, wash area gently with soap and water
Eye Contact: Rinse eyes with clean water while holding eyelids open; use clean hands to gently assist if needed
Ingestion: Rinse mouth and drink water in small sips if symptoms appear; for persistent effects consult a healthcare provider
Flammability: Not considered highly flammable, but can burn if exposed to strong ignition sources
Suitable Extinguishing Agents: Use water spray, carbon dioxide, dry powder, or foam; avoid using strong water jet directly on powder
Special Hazards: Combustion might produce nitrogen oxides or carbon oxides in smoke
Firefighter Protection: Use standard protective gear including respiration in enclosed areas
Spill Response: Gather spilled material using a HEPA-filter vacuum or wet sweeping technique to reduce dust
Personal Protection: Wear gloves, eye protection, and dust mask if cleaning larger spilled amounts
Environmental Precautions: Prevent entry into drains or water systems
Clean-up: Place spilled compound in a secure, labeled waste container for proper disposal
Handling: Minimize dust formation, keep containers tightly sealed, and work in a well-ventilated area
Prevent Contact: Use gloves and protective clothing if frequent handling expected
Storage Conditions: Store in a cool, dry, well-ventilated environment separate from strong acids or oxidizers
Container Suitability: Glass or plastic containers with tight lids work well and prevent moisture contamination
Workplace Controls: Laboratory hoods or local exhaust ventilation reduce airborne dust risk
Personal Protective Equipment: Gloves resistant to chemicals, protective eyewear, and laboratory coats minimize skin or eye contact
Respiratory Protection: Use dust mask or respirator if working near powder clouds or handling large quantities
Exposure Limits: Not specifically indexed as hazardous with set occupational exposure limits, but standard chemical safety applies
Form: Solid, crystalline powder
Color: White to pale yellow
Odor: Essentially odorless
Boiling Point: Data limited for salt form
Melting Point: Typically decomposes before melting, around 222–226°C
Solubility: Rapidly dissolves in water, low solubility in many organic solvents
pH of Solution: Slightly acidic due to hydrochloride, useful in some analytical protocols
Chemical Stability: Stable in closed containers under normal conditions
Conditions to Avoid: Excessive moisture, strong oxidizers, extreme heat
Hazardous Reactions: Low reactivity with most materials; avoid mixing with highly reactive chemicals
Decomposition Products: Exposure to high heat releases nitrogen oxides or hydrogen chloride gas
Routes of Exposure: Inhalation of fine dust, accidental skin or eye contact, rare ingestion
Short-Term Health Effects: Possible irritation, no significant poisoning observed in acute studies
Chronic Exposure: Sparse evidence on chronic effects, but not flagged as long-term hazard by major agencies
Sensitization: Risk of allergic reaction considered low
Carcinogenicity: Not classed as a cancer risk in humans
Environmental Fate: Biodegradable in soil and water, so poses little risk in accidental releases if diluted
Aquatic Impact: High concentrations could disrupt small aquatic organisms, though toxicity rated as low
Persistence: Breaks down naturally under typical environmental conditions
Safe Disposal: Collect unused material in well-labeled, sealed containers for disposal as chemical waste, use licensed disposal contractors for large quantities
Disposal of Solutions: Dilute small quantities can flow into laboratory drain systems with water unless local rules restrict
Regulatory Guidance: Follow institutional and regional requirements for chemical waste handling, especially for larger batches
Transport Regulations: Not flagged by typical transport agencies as hazardous cargo
Packing Requirements: Use robust, sealed packets or jars to prevent spillage or moisture ingress
Accidental Release: If packet ruptures, contain and clean up in the field using personal protection
Workplace Oversight: Subject to general chemical safety regulations in laboratories and manufacturing
Special Restrictions: Largely unregulated but included in routine laboratory audits
User Responsibility: Safe handling, use, and disposal fall to the end user and employer under health and safety rules
