Frequently Asked Questions
No, its commercial production and use have been banned or severely restricted in most countries since the 1960s-1970s due to its potent carcinogenicity.
They are isomers. Alpha-naphthylamine (1-naphthylamine) has the amino group on a different carbon of the naphthalene ring. While also hazardous, beta-naphthylamine is considered significantly more carcinogenic.
Primarily in the synthetic dye and pigment industry, where it was used as an intermediate in the production of azo dyes.
Through industrial hygiene monitoring (air sampling), biological monitoring (testing urine for metabolites), and medical surveillance of historically exposed populations.
