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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Coupling reaction products of diazotized 2-amino-6-[(2-substitued ethyl)sulfonyl]naphthalene-1-substituted acid with 4-({4-chloro-6-[ethyl(3-{[2-(substituted oxy)ethyl]sulfonyl}phenyl)amino]-heteromonocycl-2-yl}amino)-5-hydroxynaphthalene-2,7-disubstituted acid and their sodium and potassium salts
EC number: - | CAS number: -

Description of key information
The solubility of the substance in water is very good and the solubility in octanol is poor. The octanol-water partitioning coefficient hence is anticipated to be very small.
Key value for chemical safety assessment
- Log Kow (Log Pow):
- -4.2
- at the temperature of:
- 22.4 °C
Additional information
Neither the HPLC method according to OECD Guideline No. 117 nor the flask-shaking method according to OECD Guideline No. 107 were applicable for the determination of the partition coefficient of FAT 40850/A TE.
Thus, the log Pow-value for the test item was estimated from its solubility in n-octanol and in water, respectively:
log Pow = log (8.9 [mg/L] / 128094.3 [mg/ L]) = -4.2.
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.
