Molecular Formula: C3H4Cl2O2
CAS Number: 116-26-7
Appearance: Clear, colorless liquid with a pungent, harsh odor
Uses: Primarily found in research environments for synthesis, not in consumer products
GHS Classification: Harmful if swallowed, causes skin and eye irritation, may cause respiratory irritation
Pictograms: Exclamation mark
Signal Word: Warning
Potential Health Effects: Inhalation may trigger coughing, throat discomfort, or even headaches; skin contact can bring about redness or dryness; ingestion risks nausea, abdominal pain
Component: Methyl Dichloroacetate – 100%
Inhalation: Remove person to fresh air. Seek medical help if symptoms worsen.
Skin Contact: Rinse with soap and plenty of water. Remove contaminated clothing.
Eye Contact: Flush cautiously with water for several minutes. Take out contact lenses.
Ingestion: Rinse mouth thoroughly. Do not induce vomiting. Get medical attention if feeling unwell.
Suitable Extinguishing Media: Dry chemical, carbon dioxide, alcohol-resistant foam
Hazardous Combustion Products: Hydrogen chloride, phosgene, carbon monoxide, carbon dioxide
Precautions for Firefighters: Wear full protective gear including a self-contained breathing apparatus since toxic fumes can release easily.
Personal Precautions: Use chemical-resistant gloves and goggles. Provide good ventilation.
Environmental Precautions: Prevent spillage from entering drains or waterways
Clean-up Methods: Contain and soak up spill with inert absorbent material like vermiculite. Collect in sealed container for proper disposal. Clean area thoroughly.
Handling: Work only in well-ventilated spaces. Avoid coming into direct contact with liquid or vapor. Always secure caps tightly after use.
Storage: Store in a cool, dry spot away from strong oxidizers, acids, and sources of heat or flame. Keep containers closed when not in use.
Engineering Controls: Fume hood or local exhaust strongly recommended
Eye Protection: Chemical splash goggles
Skin Protection: Impermeable gloves, lab coat
Respiratory Protection: Use an approved respirator if exposure levels rise above comfort
Hygiene: Wash hands after handling. Avoid eating or drinking around the material.
