In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Preparation and characterization of 2-amino-5,6-dichloro- and 2-amino-6,7-dichlorobenzothiazole, published in 1971, which mentions a compound: 25150-27-0, mainly applied to benzothiazoles amino via anilines; amino chloro benzothiazoles separation; anilines thiocyanation benzothiazoles, Quality Control of 6,7-Dichlorobenzo[d]thiazol-2-amine.
A mixture of 2-amino-5,6-dichlorobenzothiazole (I) and 2-amino-6,7-dichlorobenzothiazole (II) is prepared by the reaction of 3,4-dichloroaniline (III) with thiocyanogen. 2-Amino-4,5-dichlorophenyl thiocyanate and 6-amino-2,3-dichlorophenyl thiocyanate are the intermediates of I and II. Thus, III is treated with KSCN, thiocyanogen is formed by the addition of Br, and the I-II mixture obtained is separated via HCl salt formation. NMR spectra are given.
In some applications, this compound(25150-27-0)Quality Control of 6,7-Dichlorobenzo[d]thiazol-2-amine is unique.If you want to know more details about this compound, you can contact with the author or consult more relevant literature.
