Hazard InformationBack Directory
[General Description]

A yellow oily liquid with an offensive odor. Insoluble in water. Density 1.72 g/cm3. Hence sinks in water. Nonflammable but supports combustion. Very toxic by inhalation or skin absorption.
[Reactivity Profile]

PERCHLOROMETHYL MERCAPTAN(594-42-3) is incompatible with acids, diazo and azo compounds, halocarbons, isocyanates, aldehydes, alkali metals, nitrides, hydrides, and other strong reducing agents. Reactions with these materials generate heat and in many cases hydrogen gas. Reacts readily with oxidizing agents.
[Air & Water Reactions]

Insoluble in water. Slowly decomposed by moisture in the air. Reacts with hot water to give carbon dioxide, hydrochloric acid and sulfur.
[Health Hazard]

May cause death or permanent injury after short exposure to small quantities, strong irritant to eyes and skin. Inhalation may cause severe irritation of the upper respiratory tract. It also is a strong irritant to the eyes and skin. Brief exposure to lower concentrations may produce central nervous system depression and lung, liver, and heart congestion. Severe exposures may be fatal. Exposure of eyes may lead to severe conjunctivitis or corneal damage. The liquid is irritating to the skin, and may be absorbed through the skin in quantities sufficient to cause general toxic effects. Ingestion may cause damage to mucous membranes and result in pain and burning of the mouth and throat, nausea, vomiting, cramps, and diarrhea. In severe cases, tissue ulceration and CNS depression may occur.
[Potential Exposure]

Perchloromethyl mercaptan is used as an intermediate for the synthesis of dyes and fungicides, such as Captan and Folpet. This chemical has been considered as a warfare tear gas because of its highly irritant properties.
[Fire Hazard]

Very irritating vapors formed from hot material; may form phosgene gas, hydrogen chloride, and sulfur dioxide. At high temperatures this compound will decompose to carbon tetrachloride, sulfur chloride, heavy oil polymers, phosgene gas, hydrogen chloride, and sulfur dioxide. Reacts with iron or steel, evolving carbon tetrachloride. Corrosive to most metals. Reacts with water only when hot to give carbon dioxide, hydrochloric acid, and sulfur. Hazardous polymerization may not occur.
[First aid]

If this chemical gets into the eyes, remove any contact lenses at once and irrigate immediately for at least 15 minutes, occasionally lifting upper and lower lids. Seek medical attention immediately. If this chemical contacts the skin, remove contaminated clothing and wash immediately with soap and water. Seek medical attention immediately. If this chemical has been inhaled, remove from exposure, begin rescue breathing (using universal precautions, including resuscitation mask) if breathing has stopped and CPR if heart action has stopped. Transfer promptly to a medical facility. When this chemical has been swallowed, get medical attention. Give large quantities of water and induce vomiting. Do not make an unconscious person vomit
[Shipping]

UN1670 Perchloromethyl mercaptan, Hazard Class: 6.1; Labels: 6.1-Poisonous materials, Inhalation Hazard Zone B.
[Incompatibilities]

Water contact forms HCl, sulfur and carbon dioxide. Reacts with alkalies, amines, hot water; alcohols, oxidizers, reducing agents; iron, and steel. Attacks most metals.
