Description of key information
Parent compound tetradecyl chloroformate and hydrolysis product tetradecanol: After evaporation or exposure to the air, the product will be rapidly degraded by photochemical processes.
This estimation refers to dry air. In mist, rain, droplets and aerosols, hydrolysis will be the major fate process of the chloroformate due to the short half-life in aqueous solution. Therefore this estimate may be of low relevance.
Key value for chemical safety assessment
Additional information
Parent compound tetradecyl chloroformate: Based on an estimated OH radical rate constant of 18.6977 E-12 cm3/(molecule*sec), the half-life of
tetradecyl chloroformate was calculated to be 0.8 days (conditions: sensitiser for indirect photolysis: OH; 0.5 E06 OH/cm3, 24-h d; BASF SE, 2012). Based on the EPI Suite calculation the substance will be rapidly degraded by photochemical processes after evaporation or exposure to air.

Hydrolysis product tetradecanol: Based on an estimated OH radical rate constant of 21.0205 E-12 cm3/(molecule*sec), the half-life of tetradecanol was calculated to be 0.9 days (conditions: sensitiser for indirect photolysis: OH; 0.5 E06 OH/cm3, 24-h d; BASF SE, 2012). Based on the EPI Suite calculation the substance will be rapidly degraded by photochemical processes after evaporation or exposure to air.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
