Key value for chemical safety assessment

Half-life in air:
42 h

Additional information

An EPI Suite v 3.12 (AopWin v1.91) calculation model was applied in order to determine a half life time of C8AS Na (CAS 142-31-4) in the air. The calculated DT50 was 42 hours. Rate constant (for indirect photolysis): = 0.0000000000092 cm³/(molecule*sec).
