Description of key information

After evaporation or exposure to the air, the product will be rapidly degraded by photochemical processes.

Key value for chemical safety assessment

Additional information

Tridecylamine, branched and linear (CAS 86089 -17 -0) is a mixture composed of (predominantly) groups of isomers with chain lengths ranging from C11 to C14 and, to a minor content, of C10 alkylamines. The main fraction (68%) are C13 -amines, followed by the C12 - (16%), C11 - (C12%) and C14 -amines (3%).

There is an AOP v1.92 calculation available for the estimation of the photodegradation in the atmosphere (read across from the analogue C13 substance 1 -Tridecanamine; CAS 2689 -34 -3). The calculated rate constant is 47.1E-12cm³/molecule-sec results in a half-life in the atmosphere of 8.2 hours.

For this calculation, a 24 -hour day as well as a sensitizer-concentration (OH-radicals) of 0.5E06 molecules/cm³ were assumed.

The target substance Tridecylamine, branched and linear (CAS 86089 -17 -0) is assumed not to be stable in the atmosphere.
