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.

Additional information

Indirect photodegradation of N-Acetyl-DL-tryptophan (CAS 87-32-1) in air is not expected since the substance is not likely to be present in the atmosphere (vapour pressure = < 4.6E-10 hPa, 20 °C). Furthermore, experimental findings showed that the substance is hydrolytically stable at pH values ranging from 4 to 9. Moreover, the substance is rapidly biodegradable and is thus expected to be ultimately eliminated through biodegradation by microorganisms in aquatic and terrestrial environments.
