Oily liquid. Melting point 10.2°C, boiling point 154°C (4.8 kPa), 126°C (1.33 kPa), relative density 1.3383 (20/4°C), refractive index 1.5565. Soluble in hot alcohol, ether, and benzene, insoluble in water. | [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. |
