Chemical name: N-Butyl Chloroformate
Common uses: Organic synthesis projects, lab reagent
Appearance: Clear, colorless to pale yellow liquid
Odor: Pungent, strong chemical smell
Molecular formula: C5H9ClO2
Synonyms: Butyl chloroformate
CAS Number: 592-85-8
Main dangers: Corrosive, toxic if inhaled or touched, strong irritant for skin, eyes, and respiratory system
Health impacts: Can cause chemical burns on contact, breathing in vapors brings risk of lung damage
Flammability: Not the most flammable chemical on the shelf but still may create hazardous vapors in heat
Reactivity: Reacts with moisture to release harsh gases like hydrogen chloride
Environmental danger: Toxic for fish and other aquatic life
Main component: N-Butyl Chloroformate, usually at 98–100% purity
Impurities: Trace-level byproducts from synthesis process, not significant for general handling
Inhalation: Get away from vapors right away, move to fresh air, support breathing, seek medical help
Skin contact: Pull off contaminated clothes, rinse skin with cool water for at least 15 minutes, don’t rely on wiping, get medical help fast
Eye contact: Wash eyes with water, plenty of it, don’t rub, get trained medical care
Swallowing: Don’t try to throw up, rinse mouth, get emergency medical help
Suitable extinguishing agents: Dry chemical, CO2, foam, avoid routine water stream on burning material
Fire risks: Can release toxic gases and vapors if burned, such as phosgene, hydrogen chloride
Protection: Wear full gear, including self-contained breathing apparatus—regular firefighter masks won’t cut it
Special advice: Cool any exposed containers with water to prevent pressure buildup
Small spills: Keep everyone away who isn’t needed, ventilate, absorb with sand or non-flammable absorbent, shovel into containers
Large releases: Evacuate, suit up with chemical splash gear and proper masks, coordinate with hazmat teams
Clean-up: Work only in well-ventilated spaces, avoid water if possible due to reactivity
Personal safety: Don’t go bare-handed, always use chemical gloves, eye protection, and respiratory gear
Handling tips: Work only in a working fume hood or open-air setup, wear splash goggles, gloves, keep containers closed
Storage needs: Give it a cool, dry, and well-ventilated spot, lock it away from moisture, acids, bases, and things that set off reactions
Incompatible stuff: Water and strong oxidizers especially, they’re asking for trouble
Labeling: Mark containers, give clear hazard warning signs
Engineering: Fume hoods, good fans, tightly managed air controls
Personal gear: Nitrile gloves, chemical splash goggles, face shield, long-sleeved chemical-resistant lab coat
Breathing protection: Approved organic vapor respirator as a backup where engineering controls don’t handle fumes
Hygiene: Wash hands before eating or drinking, no snacks or drinks in work areas, use a sink dedicated for chemical use
Physical state: Liquid at room temperature
Color: Clear to slightly yellow
Boiling point: About 106°C
Melting point: Below room temperature, stays liquid
Vapor pressure: Higher than water, vapors can build up in closed spaces
Solubility: Breaks down in water, reacts quickly
Density: About 1.05 g/cm³
Chemical stability: Holds up under recommended storage settings
Dangerous reactions: With water, acids, bases, or strong oxidizers; makes heat, gas, and spills happen
Keep away from: Humid areas, open flames, direct sunlight, and metals that can speed up breakdown
Routes of exposure: Eyes, skin, breathing, accidental swallowing
Harmful effects: Burning pain, cough, breathing trouble, even fluid in the lungs with bad exposure
Chronic risks: No clear-cut links to cancer or birth defects known so far, though with anything this harsh, caution makes sense
Acute toxicity: Inhalation may leave lasting effects, even low vapor levels hurt over time
Toxicity: Dangerous for aquatic creatures, can kill fish and river bugs if spilled in water
Breakdown: Reacts with water, doesn’t last long outdoors, but until it’s neutralized still threatens wildlife
Bioaccumulation: Not known to build up in food chains
Spill advice: Avoid dumping into drains or natural water sources, keep it far from the environment
Preferred route: Give all waste to licensed chemical disposal services
Drains: Never flush leftovers or wash-down water
Container handling: Rinse cautiously, treat as hazardous, label leftovers for responsible disposal
Environmental preservation: Make sure no accidental mixing with general lab trash
Shipping category: Regulated as hazardous material
Container needs: Leak-proof, tightly sealed, upright containers
Symbols: Transport labels for toxic, corrosive, and environmentally harmful substances
Transit advice: Avoid heat, keep shipments well-cushioned and upright, track all movements
Hazard laws: Sits on chemical lists overseen by occupational safety and environmental offices in most countries
Worker protections: Rules require training, proper labeling, personal gear, and emergency plans
Community safety: Any big user or transporter has a duty to make neighbors and first responders aware
International shipment: Bound by treaties that control exports of potentially dangerous chemicals
