Saprikina, V. A. et al. published their research in O’zbekiston Kimyo Jurnali in 2001 | CAS: 1843-21-6

N-Phenylbenzo[d]thiazol-2-amine (cas: 1843-21-6) belongs to thiazole derivatives. Thiazoles frequently appear in peptide studies. Thiazoles can also be used as protected formyl groups, which can be released in later stages of complex natural product synthesis. There are numerous natural products that possess a thiazole ring with broad pharmacological activities. Thiamine, also known as vitamin B1, possesses a thiazole ring linked with 2-methylpyrimidine-4-amine as hydrochloride salt.HPLC of Formula: 1843-21-6

Synthesis of sulfonamides of 2- and 3-substituted benzothiazoles was written by Saprikina, V. A.;Ambartsumova, R. F.;Sultankulov, A.. And the article was included in O’zbekiston Kimyo Jurnali in 2001.HPLC of Formula: 1843-21-6 This article mentions the following:

The reactions of 2-alkyl(phenyl)aminobenzothiazoles and 2-imino-3-methyl(phenyl)benzothiazolines with benzenesulfonyl chloride gave, resp., I (R = Me, Et, Pr, Bu, Ph) and II (R = Me, Ph). In the experiment, the researchers used many compounds, for example, N-Phenylbenzo[d]thiazol-2-amine (cas: 1843-21-6HPLC of Formula: 1843-21-6).
