Nature:
1,2-dimethyl-1H-imidazole-4-sulfonyl chloride is a colorless to light yellow oily liquid with a strong pungent odor. It is insoluble in water but miscible with organic solvents such as dichloromethane, ether and methanol. Its boiling point is about 107°C.

Use:
1,2-dimethyl-1H-imidazole-4-sulfonyl chloride is an important intermediate compound. It can be used to synthesize drugs that lower blood sugar in diabetics. In addition, it is also used in the synthesis of pesticides, dyes and other organic compounds.

Preparation Method:
1,2-Dimethyl-1H-imidazole-4-sulfonyl chloride can be synthesized by the following steps:
1. First, sodium 1,2-dimethyl -1H-imidazole-4-sulfonyl chloride is reacted with a nitroso compound to generate nitrosimidazole sulfonate.
2. Then, the nitrosimidazole sulfonate is reacted with sulfuryl chloride to generate 1,2-dimethyl-1H-imidazole-4-sulfonyl chloride.

Safety Information:
1,2-Dimethyl-1H-imidazole-4-sulfonyl chloride is irritating and corrosive. Wear appropriate protective gloves, glasses and protective clothing when in use, and ensure that the operation is carried out in a well-ventilated place.
