Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
As reported in the summary of environmental fate and exposure in HSDB Report of 2 -ethylaniline by Scientific Review Committee and mentioned also in Chemical Information Profile for Alkylaniline NTP 2009 general considerations regarding 2-ethylaniline should be done:
Stability:
2-ethylaniline primarily exists in air as a vapor (based on vapor pressure= 0.17 mmHg at T=25°C) that will degrade by reaction with photochemically produced hydroxyl radicals (half-life of 3 hours). 2-Ethylaniline is not expected to undergo hydrolysis in the environment due to the lack of hydrolyzable functional groups
Biodegradation:
No data are reported in HSDB Report of 2 -ethylaniline or in Information Profile for Alkylaniline NTP 2009 . However no ready biodegradability is predicted for 2-ethylaniline by BIOWIN v.4.10.
Bioaccumulation:
An estimated BCF of 4.4 suggests the potential for bioconcentration for 2 -ethylaniline in aquatic organisms is low.
Transport and distribution
2-ehylaniline is expected to also be present in the protonated form in moist soils (based on pKa value= 4.3) and to strongly bind to soil surfaces and not volatilize. Anilines in general bind to humic material in soil, which decreases their mobility. In water 2-ethylaniline may be adsorbed by sediment and suspended solids.
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.
