(2-Chlorophenyl)methanethiol(CAS: 39718-00-8)

(2-Chlorophenyl)methanethiol is a colorless to yellow liquid with a molecular weight of 152.59 g/mol. It has a low solubility in water (0.15 g/100 mL at 20°C) but is more soluble in organic solvents. It is moderately reactive, particularly with alcohols and amines, and may undergo substitution reactions. Its crystalline form is not common, but it can exist as a solid at very low temperatures.

(2-Chlorophenyl)methanethiol can be synthesized via the addition of hydrogen sulfide to 2-chlorophenylmethanol or by the reduction of 2-chlorophenylmethanone with hydrogen and a suitable catalyst. The reaction conditions can vary, but typically involve mild conditions to avoid over-reduction or decomposition. Yield and selectivity are generally good, making it a reliable method for industrial production.

(2-Chlorophenyl)methanethiol is used in the pharmaceutical industry for the synthesis of various medicinal compounds, in polymer applications for functionalization, in gas sensors for detecting specific gases, and in semiconductor manufacturing for cleaning and etching processes. Its unique chemical properties make it valuable in these fields.

When handling (2-Chlorophenyl)methanethiol, it is crucial to wear appropriate personal protective equipment (PPE) such as gloves, goggles, and a lab coat. Work should be conducted in a well-ventilated area or a fume hood. Spills should be cleaned up with an appropriate neutralizing agent and proper disposal methods. Always refer to the Safety Data Sheet (SDS) for detailed safety information and emergency procedures.
