Product Name:2,5-Dimethyl-4-methoxybenzenesulfonyl chloride
English Name:2,5-Dimethyl-4-methoxybenzenesulfonyl chloride
CAS No.:91179-12-3
Aliases:4-Methoxy-2,5-dimethylbenzenesulfonyl chloride, 2,5-Dimethyl-4-methoxybenzene-1-sulfonyl chloride
Molecular Formula:C9H11ClO3S
Physical Properties:White to light yellow crystalline solid at room temperature; density approximately 1.2 g/cm³ (estimated); hydrolyzes in the presence of water or moisture, releasing hydrogen chloride gas. Easily soluble in organic solvents such as dichloromethane, chloroform, ethyl acetate, and toluene; slightly soluble in water. Decomposes upon heating or open flame; can be distilled under reduced pressure.
Uses:This product is an important organic synthesis intermediate, commonly used to introduce the 2,5-dimethyl-4-methoxybenzenesulfonyl group into target molecules for preparing corresponding sulfonamides, sulfonate esters, and sulfones. It is also used in pharmaceutical synthesis to construct sulfonamide-containing active molecules, as well as in the synthesis and modification of dyes, agrochemicals, and fine chemicals.
Technical Specifications:
Molecular formula: C9H11ClO3S; molecular weight: 234.70
Appearance: white to light yellow crystalline solid or powder
Purity: not less than 98%
Solubility: easily soluble in dichloromethane, chloroform, and other organic solvents; slowly hydrolyzes in water
Storage: keep sealed, dry, and cool, protected from moisture
