Description of key information

T1/2 = 6.8 h (sensitizer OH radical) (AOP Win v1.86)

Key value for chemical safety assessment

Half-life in air:
6.8 h
Degradation rate constant with OH radicals:
56.617 cm³ molecule-1 s-1

Additional information

No studies investigating the indirect photolysis of 2-amino-1,3-propanediol (APD) are available. Using AOP Program (v1.92), a half-life of 6.8 hours was calculated, indicating rapid degradation by indirect photolysis.
