EC number: 226-109-5
CAS number: 5281-04-9
The half-life of the test chemical calcium 3-hydroxy-4-[(4-methyl-2-sulfonatophenyl)diazenyl]-2-naphthoate (CAS no. 5281-04-9) was determined at different pH range. The study was performed according to OECD Guideline 111 (Hydrolysis as a Function of pH) at a temperature of 50°C. Although, half-life value of test chemical is not known, but chemical calcium 3-hydroxy-4-[(4-methyl-2-sulfonatophenyl)diazenyl]-2-naphthoatewas reported to be hydrolytically stable at pH 4, 7 and 9, respectively and at a temperature of50⁰C. Based on this, it is concluded that the chemical calcium 3-hydroxy-4-[(4-methyl-2-sulfonatophenyl)diazenyl]-2-naphthoateisnot hydrolysable.
