Description of key information
Additional information
Stability
Phototransformation in air
Parent compound propyl chloroformate (CAS 109-61-5):
After evaporation or exposure to air, the substance will be slowly 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 substance due to the short half-life in aqueous solutions. Therefore this estimate may be of low relevance.
Hydrolysis product propanol (CAS 71-23-8):
After evaporation or exposure to air, the substance will be slowly degraded by photochemical processes.
Hydrolysis
Parent compound propyl chloroformate (CAS 109-61-5):
In contact with water, the substance will hydrolyse rapidly.
Hydrolysis product propanol (CAS 71-23-8).
According to structural properties, hydrolysis is not expected.
Biodegradation
Parent compound propyl chloroformate (CAS 109-61-5):
Hydrolyses rapidly (half-life = 29.5 min)
Hydrolysis product propanol (CAS 71-23-8):
Readily biodegradable according to OECD criteria.
Bioaccumulation
Parent compound propyl chloroformate (CAS 109-61-5):
Significant accumulation in organisms is not to be expected.
Hydrolysis product propanol (CAS 71-23-8):
Significant accumulation in organisms is not to be expected.
Transport and distribution
Adsorption / desorption
Parent compound propyl chloroformate (CAS 109-61-5)
Adsorption to the solid soil phase is not expected. However, propyl chloroformate (CAS 1409-61-5) rapidly decomposes in water. Therefore, the model calculation may be of low relevance.
Hydrolysis product propanol (CAS 71-23-8).
Adsorption to the solid soil phase is not expected.
Henry's Law Constant
Parent compound propyl chloroformate (CAS 109-61-5):
From the water surface, the substance will rapidly evaporate into the atmosphere. However, propyl chloroformate is rapidly hydrolysed to propanol, CO2 and HCl.
Hydrolysis product propanol (CAS 71-23-8).
From the water surface, the substance will not evaporate into the atmosphere.
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.
