The compound hydrogen chloride has the formula HCl. At room temperature, it is a colorless gas, which forms white fumes of hydrochloric acid upon contact with atmospheric humidity. Hydrogen chloride gas and hydrochloric acid are important in technology and industry.

Because of its acidic nature, hydrogen chloride is a corrosive gas, particularly in the presence of any moisture. Inhalation of the fumes can cause coughing, choking, inflammation of the nose, throat, and in severe cases, pulmonary edema, circulatory system failure, and death. Skin contact can cause redness, pain, and severe skin burns.

Most hydrogen chloride is used in the production of hydrochloric acid. It is also an important reagent in other industrial chemical transformations, such as the hydrochlorination of rubber and production of vinyl and alkyl chlorides.

Hydrogen Chloride can be detected with an equallivant detector. Bare in mind that HCL is corrosive and therefore a polycarbonate housed detector is recommended. For the right instrument, use the instrument selector or contact one of our sales representatives.
