Description of key information

The atmospheric oxidation half-life of 5-nitrosalicylic acid was estimated using the level III multimedia model. It was estimated that the substance is persistent in air medium as the half life period of 5-nitrosalicylic acid in air is 7.1 days. This indicates that 5-nitrosalicylic acid is not rapidly phototransformed in air.

Key value for chemical safety assessment

Half-life in air:
7.1 d
