Hexyl chloroformate

Endpoint summary

Additional information

Hexyl chloroformate is expected to rapidly hydrolyse in contact with water to form hexanol (CAS 111 -27 -3), hydrogen chloride (CAS 7647-01-0) and carbon dioxide (CAS 124-38-9). Therefore, the relevant key aquatic toxicity data for both the parent substance and for the hydrolysis products is tabulated below.
