Substance Name: Chlorohexane
Chemical Formula: C6H13Cl
Common Synonyms: 1-Chlorohexane, n-Hexyl chloride
Appearance: Colorless to pale yellow liquid
Odor: Sweet, ether-like
Use: Often finds a role in organic synthesis labs and industrial chemical processes, not something you encounter outside specific workplaces.
Classification: Flammable liquid and vapor, irritant to skin, eyes, and airways
Hazard Pictograms: Flame, exclamation mark, environment (if included for aquatic harm)
Signal Word: Warning
Major Risks: Catching fire when exposed to heat or open flame, causing skin/blindness issues on contact, giving headaches or dizziness after breathing it in for a short while, leading to worse organ problems with heavy or repeat exposure. Chlorohexane doesn’t just affect people on contact; vapors work their way around poorly ventilated rooms, causing harm without much warning.
Main Component: Chlorohexane
Chemical Purity: Typically over 98% in most chemical labs
CAS Number: 544-10-5
Impurities: Minor traces of other hexane derivatives (depending on manufacturing quality)
Exposure Limit: Check local and national guidelines, since some places set legal exposure limits and others do not.
Skin Contact: Wash with soap and water for at least 15 minutes. Remove contaminated clothing. For burns or irritation, see a doctor.
Eye Contact: Rinse eyes with clean water for several minutes. A trip to an eye specialist protects against permanent damage.
Inhalation: Move the person somewhere with clean air. If breathing problems stick around, call for professional help.
Ingestion: Rinse mouth fully but don’t try to vomit unless a doctor says so.
Many solvents burn more than people expect, and some health issues creep up after exposure, which is why fast action matters.
Suitable Extinguishing Media: Foam, carbon dioxide, dry chemical powder
Specific Hazards: Vapors explode under air/oxygen and fire. Dense poisonous fumes, such as hydrogen chloride and phosgene, come from burning.
Precautions for Firefighters: Wear full protective gear, positive-pressure breathing equipment. Approach fires from upwind.
Fire Fighting Tips: Cool containers with water from far away to avoid bursting. Keep out of low areas where vapors can settle.
Personal Protection: Evacuate untrained people. Wear chemical-resistant gloves and goggles, splash apron, and a good mask or use a vented area.
Spill Response: Contain liquid with non-flammable absorbents like sand or special chemical mats. Shovel up and bag the material for approved disposal.
Environmental Protection: Stop chemicals from running into sewers, rivers, or soil. Even a small spill can upset a waterway or soil patch for much longer than most figure at the time.
Safe Handling: Keep drums and bottles shut tight unless in use. Work in areas with good airflow or under a fume hood. Avoid static, sparks, or open flames. Use proper grounding for pumps and containers.
Storage Conditions: Store well away from heat, direct sunlight, or sources of ignition. Keep in a cool, dry spot, using steel or chemical-grade plastic. Do not mix with oxidizers or acids. Label clear warning signs to reduce mix-ups and unsafe handling.
Personal Experience: Messy chemical storage can lead to sudden fires and ruined stocks. One misstep with a solvent like this, and you aren’t just cleaning up a puddle — you could evacuate a building.
Engineering Controls: Use chemical fume hoods, vented enclosures, and explosion-proof ventilation.
Personal Protective Gear: Wear splash goggles, solvent-resistant gloves (nitrile or neoprene outlast latex), flame-resistant lab coat, and proper respirator if handling more than a drop at a time. Close-toed shoes keep splashes off feet.
Work Practices: Wash up after handling. Don’t eat, drink, or smoke around solvents. Have an eyewash and shower nearby.
Exposure Limits: Some workplaces adopt a threshold limit value for similar solvents (Chlorohexane may not have an official value everywhere). Err on the cautious side.
Boiling Point: About 137°C (279°F)
Melting Point: About -44°C (-47°F)
Flash Point: Around 29°C (84°F), which means a simple hot day can make vapors catch fire.
Density: Close to 0.87 g/cm3 (liquid)
Vapor Pressure: Moderate at room temp
Solubility: Barely dissolves in water, but easy to mix with most organic solvents.
Odor Threshold: Noticeable at low parts per million, which can help give early warning of a leak.
Stable Under: Normal room temperatures and pressures if containers stay sealed and dry.
Incompatibility: Oxidizing agents, strong acids, alkali metals — reactions with these can make explosions or toxic fumes.
Decomposition Products: Hydrogen chloride, phosgene, and carbon monoxide can sneak out if heated or caught in a fire.
Reactive Concerns: Long exposure to air breaks it down slowly, so old material can turn worse over time. Handling with damp hands or in wet weather can trigger slow breakdown.
Acute Effects: Skin irritation, moderate to severe eye harm, headaches, dizziness, nausea, drowsiness from inhalation. Swallowing gives abdominal pain and usually more serious problems.
Chronic Effects: Long exposures tie in with liver and kidney damage. Repeated exposure can knock out nerve health over time.
Route of Entry: Eyes, skin, mouth, breathing
Symptoms: Redness, burning, coughing, memory trouble at higher doses. Most people notice effects fast, but some symptoms lag behind.
Environmental Hazards: Harmful to aquatic life. Runoff can poison streams, rivers, and lakes. It doesn’t break down quickly, leaving harm that lingers.
Bioaccumulation: Can build up in animal tissues, possibly moving up the chain to fish and birds.
Soil Impact: Pollutes groundwater if released on land. Plants nearby seldom fare well after exposure.
Waste Treatment: Take liquid to an approved hazardous waste facility; don’t pour into drains or garbage.
Chemical Neutralization: Incineration at a licensed facility works for most loads.
Packaging: Hazmat containers with tight seals, clear hazard labels. Never reuse empty bottles.
Community Responsibility: Local collection points or scheduled hazardous waste days at city centers offer safer routes for small users and households.
UN Number: Associated with flammable liquids.
Proper Shipping Name: Chlorohexane
Hazard Class: Flammable liquid
Packing Group: Group III (for materials with a relatively low danger compared to similar chemicals)
Transport Notes: Move with spill kits, fire control media, and keep away from food, feed, and incompatible chemicals. Breakdowns or wrecks involving chemical transport always throw extra risk for nearby people and nature.
Legal Restrictions: Many regions classify Chlorohexane under workplace chemical safety laws and environmental pollution controls.
Labeling: Must carry warning icons and hazard wording, with full ingredient disclosure on workplace containers.
Worker Right-to-Know: Laws in many places require people’s access to safety sheets and proper chemical training before use.
Environmental Release: Reporting accidental releases or spills above set limits is not just good practice, but required by most environmental regulations.
