In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called Diazotization of 2,6-diaminobenzothiazole. A new process for the preparation of 2-chlorobenzothiazole reactive azo dyes, published in 1993, which mentions a compound: 2407-11-6, Name is 2-Chloro-6-nitrobenzo[d]thiazole, Molecular C7H3ClN2O2S, Product Details of 2407-11-6.
The diazotization of 2,6-diaminobenzothiazole was studied. The two amino groups could be diazotized in HCl to yield a 2-chlorobenzothiazole-6-diazonium intermediate when reacted in a standard manner. A small comparative study on the diazotization of 6-substituted 2-aminobenzothiazoles using these standard conditions was presented. The usefulness of the reaction for the preparation of 2-chlorobenzothiazole reactive dyes was outlined.
