Description of key information

Additional information

Butyl chloroformate rapidly hydrolyses in contact with water to form butanol (CAS 71 -36 -3), hydrogen chloride (CAS 7647-01-0) and carbon dioxide (CAS 124-38-9). Therefore, the relevant key data for both the parent substance and for the hydrolysis products is tabulated below.
