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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
T decomposition= 199.7°C
Key value for chemical safety assessment
Additional information
Basic Violet 1 Acetate is produced and put on the market only as acetic aqueous solution.
The analogue substance melting point was therefore tested by thermoanalysis (DSC) according to OECD 102.
An endothermic peak was observed between 30 -120°C, followed by substance decomposition between 150 -244°C. The decomposition onset is 199.7°C with an enthalpy energy of 184.7 J/g.
Based on the read across considerations the same result applies to Basic Violet 1 Acetate and decomposition is expected before melting and boiling at T < 300°C.
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.
