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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The hydrolysis of a 30% aqueous thiophosphoryl chloride solution in CD3CN was evaluated by NMR spectroscopy.
Key value for chemical safety assessment
- Bioaccumulation potential:
- no bioaccumulation potential
Additional information
The hydrolysis of a 30% aqueous thiophosphoryl chloride solution in CD3CN was evaluated by NMR spectroscopy. After 2.5 h as main components S=P(OH)2Cl and S=P(OH)3 and minor amounts of O=P(OH)2Cl and H3PO4 were found.
After 9 hours as main component S=P(OH)3 and minor amounts of O=P(OH)2Cl and H3PO4 were detected.
Due to analytical limitations of the method used, hydrogen chloride can not be detected, but the formation of HCl is predicted based on the stoichiometry of the hydrolysis reaction.
Due to the polarity and dissociation of S=P(OH)3 a high water solubility of the hydrolysis products is expected and therefore no accumulation of the hydrolysis products is assumed.
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.
