Description of key information

T1/2 = 11.5 h (sensitizer: OH radical) (AOP Win v1.86)

Key value for chemical safety assessment

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

Additional information

No studies investigating the indirect photolysis of 2-amino-2-(hydroxymethyl)-1,3-propanediol (TRIS AMINO) are available. Using AOP Program (v1.92), a half-life of 11.5 hours was calculated, indicating rapid degradation by indirect photolysis.
