Hazard Information | Back Directory | [Uses]
o-Toluenesulfonyl chloride may be used in the synthesis of:
- oxazoline
- mesityl o-tolyl sulfone
- allyl o-toluenesulfonate
- 2-methyl-4′-t-butyldiphenyl sulfone
| [Uses]
o-Toluenesulfonyl chloride is used in organic synthesis and saccharin production. It is also used as pharmaceutical intermediate. | [General Description]
o-Toluenesulfonyl chloride can be synthesized by reacting o-thiocresol in glacial acetic acid with chlorine. It participates in the preparation of 5-chloro-3-phenyl-2,1-benzisoxazole. |
