Product Name:2-Methanesulfonyl-4,6-dichloropyrimidine
English Name:2-Methanesulfonyl-4,6-dichloropyrimidine
CAS No.:4489-34-3
Aliases:2-Methylsulfonyl-4,6-dichloropyrimidine, 4,6-Dichloro-2-(methylsulfonyl)pyrimidine, 2-(Methanesulfonyl)-4,6-dichloropyrimidine
Molecular Formula:C5H4Cl2N2O2S
Physical Properties:White to light yellow crystalline powder with a pungent odor. Slightly soluble in water; readily soluble in organic solvents such as methanol, ethanol, and dichloromethane. Melting point approximately 120°C, predicted boiling point around 320°C, flash point around 150°C.
Uses:This product is an important organic synthesis intermediate, widely used in the preparation of sulfonylurea herbicides (e.g., chlorimuron-ethyl) and in the synthesis of pharmaceutical and agrochemical compounds containing a pyrimidine ring. In pesticide and pharmaceutical synthesis, it is utilized to introduce the pyrimidine skeleton or to further transform the methanesulfonyl group for constructing biologically active target molecules.
Technical Specifications:
Purity: ≥98%
Appearance: white to light yellow crystalline powder
Melting point range: 118-122°C
Loss on drying: ≤0.5%
Residue on ignition: ≤0.2%
