Purity: >98% by weight
Impurities: Minor levels of dichlorinated analogs, unreacted fatty acids below 1%
Additional Ingredients: None specified; handled as a neat compound in most laboratory and manufacturing contexts
Inhalation: Remove person to fresh air, keep warm and at rest, seek medical attention for continued breathing difficulty; provide oxygen if necessary
Skin Contact: Remove contaminated clothing immediately and wash affected skin with plenty of running water for at least 15 minutes, seek medical attention due to corrosive nature of the substance
Eye Contact: Immediately flush eyes with copious amounts of water for at least 15 minutes, lifting upper and lower eyelids; remove contact lenses if present; obtain medical assistance promptly
Ingestion: Rinse mouth with water, do not induce vomiting; seek immediate medical help as chemical burns may occur within the digestive tract
Notes for Physician: Treat symptomatically and supportively; chemical burns pose delayed risks, consider pulmonary irritation
Extinguishing Media: Use water spray, alcohol-resistant foam, dry chemical powder, or carbon dioxide
Unsuitable Extinguishing Media: Do not use water jet directly on the burning substance
Special Hazards from Fire: Emits hydrogen chloride, carbon monoxide, possibly dioxins, and carbon dioxide under combustion; reacts with water to release hydrogen chloride gas
Fire Fighter Protection: Use full protective clothing and self-contained breathing apparatus; approach fire from upwind
Hazardous Combustion Products: Hydrogen chloride, various volatile organic compounds, possible carbon oxides released during incineration
Personal Precautions: Evacuate area, ventilate space, avoid skin and eye contact, prevent inhalation of fumes; only trained personnel with chemical-resistant gloves and goggles should conduct clean-up
Environmental Precautions: Prevent entry into drains, surface, and groundwater; absorb spills with inert material such as sand or vermiculite
Spill Cleanup Method: Neutralize spill with sodium bicarbonate or lime, scoop residues to suitable waste container, clean contaminated surfaces with plenty of water; dispose of according to local regulations
Decontamination: Use sodium bicarbonate solution for further neutralization; check pH to ensure neutral before final disposal
Safe Handling: Use with adequate ventilation, avoid inhaling vapors and contact with skin and clothing; use in a dedicated chemical fume hood; do not handle near moisture sources; static discharge precautions advised
Storage Condition: Keep container tightly closed in a cool, dry, well-ventilated area away from sources of heat and incompatible materials such as water, strong bases, and alcohols
Incompatible Materials: Strong oxidizers, alcohols, bases, ammonia, water/glycol solutions can cause exothermic reactions
Packaging: Store only in materials resistant to strong acids and chlorinated substances; avoid metal containers that may corrode
Exposure Limits: No established occupational exposure limits; treat as corrosive chemical
Engineering Controls: Mechanical ventilation, chemical fume hood, local exhaust
Personal Protective Equipment: Chemical-resistant gloves (nitrile, neoprene), impervious clothing, splash-proof goggles, face shield; respirator with acid gas canisters if airborne concentrations may exceed guideline
Hygiene Measures: Wash hands and face thoroughly after handling, change contaminated clothing promptly, avoid eating or drinking while handling
Appearance: Colorless to pale yellow oily liquid
Odor: Penetrating, acrid, characteristic acid halide
Odor Threshold: Not established
pH: Strongly acidic in contact with water
Melting Point: 22–24°C
Boiling Point: 125–130°C at 15 mmHg
Flash Point: Not available (decomposes before boiling at standard pressure)
Ignition Temperature: Not determined
Evaporation Rate: Not available
Flammability: Not classified as highly flammable but forms irritating and corrosive fumes
Vapor Pressure: 0.1 mmHg at 20°C
Vapor Density: Not measured
Solubility: Reacts with water; soluble in organic solvents such as benzene, chloroform, diethyl ether
Partition Coefficient (n-octanol/water): Not measured; predicted to be hydrophobic
Decomposition Temperature: Decomposes with water at ambient/room temperatures
Viscosity: Oily, thick at room temperature
Chemical Stability: Stable in tightly closed containers and absence of moisture; decomposes rapidly in contact with water
Reactivity: Highly reactive with water, bases, and alcohols
Hazardous Reactions: Violent with water, releasing hydrogen chloride gas
Conditions to Avoid: Moisture, heat, direct sunlight, open flames, incompatibles
Incompatible Materials: Water, alcohols, amines, strong bases, oxidizers, reducing agents
Hazardous Decomposition Products: Hydrogen chloride, carbon oxides upon burning or hydrolysis
Routes of Exposure: Inhalation, skin contact, eye contact, ingestion
Acute Effects: Severe burns to skin, eyes, mucous membranes; respiratory irritation and possible tissue damage
Symptoms: Redness, blistering, pain, vision impairment, pulmonary discomfort
LD50/LC50 Information: Not well defined for this compound specifically; similar acid chlorides show oral rat LD50 values ranging 200–500 mg/kg
Chronic Effects: Potential for dermatitis with chronic skin exposure, lung function impairment with repeated inhalation exposure
Carcinogenicity: Not classified as carcinogenic by IARC, NTP, or OSHA
Other Toxicological Data: No significant mutagenicity reported in available databases
Acute Aquatic Toxicity: No direct LC50 values for fish or daphnia publicly available; high reactivity causes rapid hydrolysis in water, liberating hydrogen chloride and long-chain fatty acids
Chronic Aquatic Effects: Expected to hydrolyze before bioaccumulating; hydrochloric acid formed is harmful to aquatic organisms
Mobility in Soil: Rapid hydrolysis prevents migration in groundwater
Persistence and Degradability: Short persistence due to quick chemical transformation; does not persist in aquatic environments
Bioaccumulation Potential: Unlikely due to rapid breakdown; degradation products show low bioaccumulation
Additional Hazards: Large spills to water cause pH drop and local ecotoxicity
Waste Treatment Methods: Must be neutralized before disposal to protect wastewater systems; mix carefully with an excess of sodium bicarbonate under controlled conditions
Residue Handling: Place neutralized solids and sludges in corrosive chemical waste containers for incineration or landfill at authorized hazardous waste sites
Container Disposal: Triple rinse with neutralizing solution, perforate, and dispose through chemical waste management systems
Environmental Precautions: Never dump into sewers or municipal drains, avoid releases to surface water
