Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

L-Serine is indirectly photodegraded by reaction with hydroxyl radicals in the atmosphere with a half-life of about 9.098 hours taking into account a 24 -h day and a mean OH radical concentration of 0.5E06 radicals per cm3. It does not contain chromophores that absorb at wavelengths > 290 nm and therefore is not expected to be susceptible to direct photolysis by sunlight.

L-Serine is not expected to undergo hydrolysis in the environment due to the lack of functional groups that hydrolyse under environmental conditions.

L-Serine is readily biodegradable under aerobic and anaerobic conditions.

Due to the low logKow and its physiological role L-serine is considered to have a low potential for bioaccumulation/bioconcentration in organisms.

The logKoc of L-serine is estimated to be below -1 , using the software program KOCWIN as well as using the software program ACD/LogD Suite, Version 12.0. This indicates a high mobility in soil.

L-Serine exists as zwitterion in the environment. Volatilization from moist soil surfaces and water surfaces will not occur as ionic compounds do not volatilize.
