Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 estimated (EPI suite, 2016) bioconcentration factor (BCF) for 1-Naphthalenecarboxaldehyde, 2-hydroxy-, (2-hydroxy-1-naphthalenyl)methylene hydrazone is 4989 L/kg, that exceed the bioconcentration threshold of 2000. Thus it is concluded that 1-Naphthalenecarboxaldehyde, 2-hydroxy-, (2-hydroxy-1-naphthalenyl)methylene hydrazone is expected to bioaccumulate in the food chain because it exceed the BCF criteria.
Key value for chemical safety assessment
- BCF (aquatic species):
- 4 989 L/kg ww
Additional information
A number of studies for the test compound C.I. Pigment Yellow 101(CAS no 2387-03-3) and its predicted data were reviewed for the bioaccumulation end point which are summarized as below:
The estimated (EPI suite, 2016) bioconcentration factor (BCF) for 1-Naphthalenecarboxaldehyde, 2-hydroxy-, (2-hydroxy-1-naphthalenyl)methylene hydrazone is 4989 L/kg, that exceed the bioconcentration threshold of 2000. Thus it is concluded that 1-Naphthalenecarboxaldehyde, 2-hydroxy-, (2-hydroxy-1-naphthalenyl)methylene hydrazone is expected to bioaccumulate in the food chain because it exceed the BCF criteria.
The estimated (SciFinder, American Chemical Society (ACS); 2016) BCF values for the test chemical at 25°C are as follows: 404 at pH 1, 477 at pH 2, 1190 at pH 3, 7130 at pH 4, 26600 at pH 5, 37100 at pH 6, 36400 at pH 7, 21900 at pH 8, 2430 at pH 9, 48.8 at pH 10, respectively.
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.
