Description of key information

Hydrolysis half-life at pH 4,7, and 9 estimated to be greater than 1 year at 25°C.

Key value for chemical safety assessment

Additional information

A preliminary assessment of the hydrolytic stability of 2-Bromo-3,3,3-trifluoropropene was conducted (Huntingdon Life Sciences, 2012, study code WAG0007); the test was performed according to EC test guideline C7 and OECD method 111, and in compliance with GLP. The hydrolysis of the substance in water (nominal concentration approximately 25 mg/L) was assessed at 50°C over 10 days (240 hours); the test was conducted under acidic, neutral, and basic conditions (pH 4, pH 7, and pH 10).

At each pH condition, 2-Bromo-3,3,3-trifluoropropene was found to have hydrolysed by less than 10% by day 5; this is equivalent to a half-life of greater than 1 year at environmental conditions (25°C).

2-Bromo-3,3,3-trifluoropropene was determined to be hydrolytically stable under acidic, neutral, and basic conditions.
