Biodegradation of CAS# 756-12-7 was assessed in a closed bottle test (OECD TG301D) conducted under GLP criterion. Sodium acetate was used as reference. CAS# 756-12-7 did not measurably degrade during the test period. In toxicity controls, CAS# 756-12-7 at a concentration of 50 mg/L did not measurably prevent the reference substance from being degraded. CAS# 756-12-7 is not readily biodegradable.
The study was conducted in accord with internationally accepted guidelines under GLP criteria. It is reliable without restriction and is suitable for use in Risk Assessment, Classification & Labelling, and PBT Analysis
