2-Chlorobenzothiazole Chemical Properties,Usage,Production

Chemical Properties

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.

Uses

2-Chlorobenzothiazole was used in the synthesis of:

  • (RS)- and (S)-lubeluzole
  • (1,3-benzothiazol-2-yl) amino-9-(10H)-acridinone derivatives
  • 4H-thieno[2′,3′:4,5]pyrimido[2,1-b]benzothiazole derivatives

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).
