Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The target substance Reaction mass of 3-[(4-Amino-2-methyl-5-pyrimidinyl)methyl]-4-methyl-5-{ 2-[hydroxy(phosphonooxy)-phosphinyl]oxyethyl]-thiazoliumchlorid and 3-[( 4-Amino-2-methyl-5-pyrimidinyl)methyl]-4-methyl-5-(2-phosphonooxyethyl)- thiazoliumchlorid-Dihydrat is characterized by high water solubility (312 g/L at 20 °C, OECD 105) and a low, estimated potential for adsorption to particulate matter (log Koc = 0.77 - 0.80, pH 7, pKa 6.25/6.22, ChemProp v6.5), indicating that the substance will preferentially distribute into the water compartment and that it is mobile in water. Based on the low vapor pressure (2.4E-09 hPa at 20 °C, OECD 104) the substance is not expected to evaporate into the atmospheric compartment. Moreover, the substance is not readily biodegradable (39% ThODNH4 in 28 d/25% ThODNO3 in 28 d, OECD 301F) and hydrolytically stable for ≥ 30 d at environmentally relevant conditions (25 °C, pH 4.6 – 9.0). However, the potential for bioaccumulation is low (log Kow = -4.5 at 20 °C, OECD 105, Flask Method).
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.
