EC number: 419-480-1 | CAS number: -
At pH 9, pH 7 and pH 4 the substance is considered to be degradable abiotically over a period of time according to the EC-guideline utilised.
At pH 9, pH 7 and pH 4 the substance is considered to be degradable abiotically over a period of time according to the EC-guideline utilised. Reactive blue consists of two main compounds. The overall sum of both compounds was determined.
Experimental studies on hydrolytic effects demonstrated that the substance does undergo some hydrolysis at environmentally relevant pH’s, with a half-life of 3, 379, and 34 days at pH 4, 7 and 9, respectively, at 25 °C, based on a pseudo first order rate constant as calculated from the Arrhenius equation.
