Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Parent compound pivaloyl chloride (CAS 3282-30-2): No data available.
Hydrolysis product pivalic acid (CAS 75-98-9): with high probability acutely not harmful to algae.
Hydrolysis product HCl (CAS 7647-01-0): Acutely very toxic for aquatic algae (pH dependent).
Key value for chemical safety assessment
- EC50 for freshwater algae:
- 979 mg/L
- EC10 or NOEC for freshwater algae:
- 246 mg/L
Additional information
No data are available for the parent compound pivaloyl chloride (CAS 3282-30-2). However, the parent compound rapidly hydrolyses in contact with water and forms pivalic acid (CAS 75-98-9) and HCl (CAS 7647-01-0). Therefore, the toxicity to aquatic green algae and cyanobacteria will be assessed based on the information available for the hydrolysis products pivalic acid and HCl.
Parent compound pivaloyl chloride:
No data available.
Hydrolysis product pivalic acid:
The toxicity of the hydrolysis product pivalic acid was tested in a GLP
compliant study performed according to OECD 201 with Raphidocelis
subcapitata (previous name Pseudokirchneriella subcapitata
as test organism (Exxon, 2003). The 72-h ErC50 was found to be 979 mg/L.
The NOEC is reported to be 246 mg/L. The test item concentration was
analytically verified and effect values are therefore based on nominal
test concentrations.
Hydrolysis product HCL:
The toxicity of the hydrolysis product HCl was tested in a GLP study according to OECD 201 with R. subcapitata (previous name P. subcapitata (MITI, 1999; peer reviewed data: OECD SIDS, 2002). The 72-h ErC50 was 0.492 mg/L (acid equivalent to pH 5.3). The NOEC was 0.097 mg/L (acid equivalent to pH 6).
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.
