Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Description of key information
Additional information
Hydrolysis
Parent compound pivaloyl chloride (CAS 3282-30-2): In contact with water, the substance will hydrolyse rapidly.
Hydrolysis product pivalic acid (CAS 75-98-9): According to structural properties, hydrolysis is not probable.
Phototransformation in air
After evaporation or exposure to air, the parent compound pivaloyl chloride (CAS 3282-30-2) and its hydrolysis product pivalic acid (CAS 75-98-9) will be slowly degraded by photochemical processes.
Biodegradation
Pivaloyl chloride (CAS 3282-30-2) rapidly hydrolyses to form pivalic acid (CAS 75-98-9). The hydrolysis product pivalic acid is not readily biodegradable (according to OECD criteria).
Bioaccumulation
Significant accumulation of pivaloyl chloride (CAS 3282-30-2) and its hydrolysis product pivalic acid (CAS 75-98-9) in aquatic organisms is not to be expected.
Adsorption
Parent compound pivaloyl chloride (CAS 3282-30-2): Adsorption to the solid soil phase is not expected.
Hydrolysis product pivalic acid (CAS 75-98-9): Adsorption to the solid soil phase is not expected.
Henry's Law Constant
Parent compound pivaloyl chloride (CAS 3282-30-2): From the water surface the substance will rapidly evaporate into the atmosphere.
Hydrolysis product pivalic acid (CAS 75-98-9): From the water surface the substance will not evaporate into the atmosphere.
Distribution modelling
Parent compound pivaloyl chloride (CAS 3282-30-2): Over time, the substance will preferentially distribute into the compartment air (82.5 %) and slightly into the compartment water (17.5%).
Hydrolysis product pivalic acid (CAS 75-98-9): Over time, the substance will preferentially distribute into the compartment water (75.6 %) and slightly into the compartments air (23.6 %), sediment (0.4 %) and soil (0.4 %).
As the parent compound pivaloyl chloride (CAS 3282-30-2) rapidly hydrolyses in contact with water and forms pivalic acid (CAS 75-98-9), the assessment of environmental fate and pathways is predominantly based on the data for the hydrolysis product.
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.
