CLEAR YELLOW TO YELLOW-BROWNISH LIQUID | [Uses]
2-Chloro-1,3-benzothiazole is used in the synthesis of CBTs which are good building blocks for bioluminescent compounds for imaging. | [Purification Methods]
It is purified by fractional distillation in vacuo. The 2-chloro-3-methylbenzothiazolinium 2,4-dinitrobenzenesulfonate crystallises from Ac2O, m 162-163o(dec).
