UN Hazard Class: 6.1 UN Packing Group: II TETRAMETHYLAMMONIUM CHLORIDE ICSC: 1099 Important Data Physical State; Appearance: HYGROSCOPIC , WHITE CRYSTALS Physical Dangers: Chemical Dangers: The substance decomposes on heating above 300°C producing ammonia , carbon monoxide , hydrogen chloride and nitrogen oxides . Reacts with oxidants . Occupational Exposure Limits: TLV not established. MAK not established. Routes of Exposure: The substance can be absorbed into the body by inhalation and by ingestion. Inhalation Risk: Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly when dispersed. Effects of Short-Term Exposure: The substance is irritating to the eyes , the skin and the respiratory tract . The substance may cause effects on the central nervous system . Effects of Long-Term or Repeated Exposure: Physical Properties Melting point (decomposes): 368-370°C Density: 1.17 g/cm3 Solubility in water, g/100 ml at 20 °C: very good Environmental Data N O T E S Environmental effects from the substance have not been investigated.
