Name: Pyrrolidine Chemical Formula: C4H9N Appearance: Clear, colorless to pale yellow liquid Odor: Strong, amine-like smell Molecular Weight: 71.12 g/mol Boiling Point: Around 87°C Solubility: Easily mixes with water, alcohols, ethers
Major Hazards: Flammable, corrosive to skin and eyes, vapors can irritate respiratory system Health Effects: Contact causes burns, inhaling fumes can damage respiratory tissue, swallowing can injure digestive system Labeling: Flammable, Corrosive Risk Phrases: Causes severe burns, harmful if inhaled, risk of serious eye damage Precautions: Avoid breathing vapors, prevent skin and eye contact, keep away from heat or flame
Main Component: Pyrrolidine (pure or near-pure) Presence of Impurities: Industrial batches may carry minor traces of other amines or residual solvents, but pure pyrrolidine usually dominates the ingredient list Concentration: Typically close to 100% unless specifically diluted
Inhalation: Move outdoors, seek fresh air, loosen any tight clothing, medical attention needed for breathing trouble Skin Contact: Wash off with water for at least 15 minutes, remove contaminated clothing, see a doctor for symptoms Eye Contact: Rinse with plenty of water for at least 15 minutes, hold eyelids open, get emergency medical help Ingestion: Rinse mouth, do not induce vomiting, get medical help right away Common Sense: Improvising safety is risky; react quickly because burns and fumes hurt fast
Suitable Extinguishing Media: Carbon dioxide, dry powder, foam Hazards During Fire: Burns vigorously, releases toxic fumes including nitrogen oxides and carbon monoxide Protective Equipment: Full protective gear, self-contained breathing apparatus for firefighters Evacuation: Nearby areas may need clearing out if the fire gets intense
Personal Protection: Put on chemical-resistant gloves, safety goggles, lab coat, work in well-ventilated space Spill Cleanup: Absorb with inert material like sand or earth, shovel into sealed chemical waste drums Environmental Avoidance: Block entry to drains or water sources, collect all spilled liquid and dispose properly Ventilation: Air out area quickly because vapors are both hazardous and flammable
Handling Tips: Work with small amounts, use fume hoods, double-check personal protective equipment Storage Conditions: Keep in airtight amber glass bottles, cool dry rooms, away from sunlight, ignition sources and acids Segregation: Separate from strong oxidizers and acids Housekeeping: Clean up drips and leaks after use, store only what is needed for the job
Engineering Controls: Fume hoods, local exhaust ventilation, chemical-resistant surfaces Respiratory Protection: Proper cartridge respirators for organic vapors Skin Protection: Wear gloves made of rubber or nitrile, lab coats, possibly aprons for larger jobs Eye/Face Protection: Tight-fitting chemical splash goggles Hygiene: Wash well after handling, avoid touching face, don’t eat or drink near working areas
Form: Liquid Color: Clear to pale yellow Odor: Strong, unpleasant amine scent Boiling Point: About 87°C Melting Point: −63°C Flash Point: 27°C Specific Gravity: 0.866 at 20°C Solubility: Fully mixes with water, alcohols Vapor Pressure: High enough to require fume protection Stability Under Normal Conditions: Chemically stable in closed containers
Chemical Stability: Maintains stability in standard lab and storage settings Conditions to Avoid: Spark, flame, heat, sunlight, strong oxidizers, acids Possible Reactions: Violent reactions with acids, halogenated compounds, certain metals Hazardous Decomposition: Releases toxic gases including nitrogen oxides if overheated
Acute Effects: Inhalation irritates lungs and throat, skin burns, eye burns, short-term dizziness, headache Chronic Effects: Regular exposure damages respiratory system, skin, possibly nervous system Routes of Entry: Lungs, skin, eyes, mouth Exposure Limits: No formal OSHA standard set, but lab limits usually kept below 10 ppm Toxicity: Lower toxicity than many aromatic amines, but severe irritant
Environmental Impact: Toxic to aquatic life, larger spills pollute water Degradation: Breaks down over time in the environment, but reacts quickly with both organic and inorganic materials Mobility: Moves easily in soil and water, can reach groundwater Bioaccumulation: Not a major concern with this compound
Small Quantities: Neutralize under expert supervision, dispose through licensed chemical waste incinerators Large Quantities: Label containers, handle as hazardous chemical waste, coordinate pickup with professionals Sewer/Drain Disposal: Not allowed—keep out of municipal wastewater Reuse/Recovery: Not practical for most labs; destroy unwanted material properly
UN Number: UN1927 Hazard Class: 3 (flammable liquid), 8 (corrosive) Packing Group: II Shipping: Package in certified, tightly closed containers, keep upright, clear hazard labels visible Restrictions: Air, sea, and road transport recognize this as hazardous—always declare contents
Classification: Recognized as a hazardous substance under international transport codes Restrictions: Use and disposal often restricted by local workplace safety and chemical hazard laws Labeling: GHS/CLP warnings with required pictograms and signal words SDS Requirements: Most regions demand that workers have access to a Safety Data Sheet before handling
