Benzidine and Dichlorobenzidine Amine Detection
topic
Benzidine and 3,3-dichlorobenzidine determination uses the standard EN ISO 14362 reductive cleavage protocol with GC-MS confirmation, targeting these highly potent human bladder carcinogens that were widely used in direct dyes for cotton and are still detected in imported textiles from regions where regulatory enforcement of azo dye restrictions remains incomplete.
Role
Prioritises detection of the highest-risk carcinogenic amines in the REACH restricted list, where benzidine-based direct dyes represent legacy contamination risks in low-cost imported cotton textiles and occupational exposure risks for textile workers in countries without effective chemical restrictions.
