METHYL CHLOROACETATE ICSC: 1410 Chloroacetic acid methyl ester Methyl monochloroacetate Methyl-alpha-chloroacetate C3H5ClO2 Molecular mass: 108.53 ICSC #    1410 CAS #     96-34-4 RTECS # AF9500000 UN #        2295 EC #         607-205-00-X Types of Hazard/ Exposure Acute Hazards/ Symptoms Prevention First Aid/ Fire Fighting FIRE Flammable. Gives off irritating or toxic fumes (or gases) in a fire. NO open flames, NO sparks, and NO smoking. Dry powder, water spray, alcohol-resistant foam, carbon dioxide. Explosion Above 57°C explosive vapour/air mixtures may be formed. Above 57°C use a closed system, ventilation, and explosion-proof electrical equipment. In case of fire: keep drums, etc., cool by spraying with water. Exposure PREVENT GENERATION OF MISTS!  •Inhalation Cough. Shortness of breath. Sore throat. Ventilation, local exhaust, or breathing protection. Fresh air, rest. Refer for medical attention.  •Skin MAY BE ABSORBED! Redness. Pain. Skin burns. Protective gloves. Protective clothing. Remove contaminated clothes. Rinse and then wash skin with water and soap. Refer for medical attention.  •Eyes Redness. Pain. Blurred vision. Face shield, or or eye protection in combination with breathing protection. First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.  •Ingestion Abdominal pain. Nausea. Vomiting. Diarrhoea. Do not eat, drink, or smoke during work. Rinse mouth. Do NOT induce vomiting. Refer for medical attention. Spillage Disposal Storage Packaging & Labelling Remove all ignition sources. Collect leaking liquid in covered plastic containers. Absorb remaining liquid in sand or inert absorbent and remove to safe place. Chemical protection suit including self-contained breathing apparatus. Fireproof. Separated from food and feedstuffs and incompatible materials . See Chemical Dangers. Do not transport with food and feedstuffs. T symbol R: 10-23/25-37/38-41 S: 1/2-26-37/39-45 UN Hazard Class: 6.1 UN Subsidiary Risks: 3 UN Packing Group: I METHYL CHLOROACETATE ICSC: 1410 Important Data Physical State; Appearance: COLOURLESS LIQUID , WITH CHARACTERISTIC ODOUR. Physical Dangers: The vapour is heavier than air. Chemical Dangers: The substance decomposes on burning producing corrosive fumes including hydrogen chloride . Reacts with reducing agents and oxidants. Occupational Exposure Limits: TLV not established. MAK: 1 ppm, 4.5 mg/m3 Peak limitation category: I(1); skin absorption (H); sensitization of skin (Sh); Pregnancy risk group: D; (DFG 2004). Routes of Exposure: The substance can be absorbed into the body by inhalation of its vapour, through the skin and by ingestion. Inhalation Risk: A harmful contamination of the air can be reached rather quickly on evaporation of this substance at 20°C. Effects of Short-Term Exposure: The substance is corrosive to the skin, is severely irritating to the eyes and is irritating to the respiratory tract. Effects of Long-Term or Repeated Exposure: Physical Properties Boiling point: 129.5°C Melting point: -32.1°C Density: 1.2 g/cm3 Solubility in water, g/100 ml at 19.8°C: 5.2 Vapour pressure, Pa at 20°C: 650 Relative vapour density (air = 1): 3.7 Relative density of the vapour/air-mixture at 20°C (air = 1): 1.02 Flash point: 57°C o.c. Auto-ignition temperature: 465°C Explosive limits, vol% in air: 7.5-18.5 Octanol/water partition coefficient as log Pow: 0.76 (calculated) Environmental Data The substance is toxic to aquatic organisms.
