Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

PBT assessment
Administrative data
PBT assessment: overall result
- Name:
- butyl chloroformate
- Type of composition:
- legal entity composition of the substance
- State / form:
- liquid
- Reference substance:
- butyl chloroformate
- PBT status:
- the substance is not PBT / vPvB
- Justification:
Butyl chloroformate is expected to rapidly hydrolyse in contact with water to form butanol (CAS 71-36-3), hydrogen chloride (CAS 7647-01-0) and carbon dioxide (CAS 124-38-9). Due to this rapid hydrolysis, the assessment of the PBT/vPvB properties of the parent compound is considered to be of low relevance. As the PBT/vPvB criteria of Annex XIII do not apply to inorganic substances, only the hydrolysis product butanol is considered.
Butanol was determined to be readily biodegradable. Therefore, the substance does not fulfill the screening criteria for P/vP.
The estimated log Kow of butyl chloroformate (log Kow = 1.62) as well as the experimental log Kow of butanol (log Kow = 0.88) indicate that significant bioaccumulation in organisms is not to be expected. In addition, the estimated BCF of butanol is 3.2 L/kg (EPI Suite v4.11). It can be concluded that thesubstance is not B/vB.
Regarding “T”, chronic toxicity data are available for algae only. Chronic toxicity data are available for algae and daphnids. The lowest chronic effect valueis significantly greater than 0.01 mg/L(21-d NOEC = 4.1 mg/L; MOE Japan, 1996).In addition, all available acute toxicity values (LC/EC50) are clearly greater than 0.01 mg/L (for details see IUCLID chapter 6.1). The substance is concluded to be “not T”
In conclusion, butyl chloroformate (CAS 592-34-7) is not to be considered as a PBT/vPvB substance.
