2-Chlorobenzothiazole Usage And Synthesis |
Chemical Properties | CLEAR YELLOW TO YELLOW-BROWNISH LIQUID |
Uses | 2-Chlorobenzothiazole was used in the synthesis of: (RS)- and (S)-lubeluzole(1,3-benzothiazol-2-yl) amino-9-(10H)-acridinone derivatives4H-thieno[2′,3′:4,5]pyrimido[2,1-b]benzothiazole derivatives |
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).
