Product Name:3-Cyano-4-methyl-2,6-dichloropyridine
English Name:3-Cyano-4-methyl-2,6-dichloropyridine
CAS No.:875-35-4
Aliases:2,6-Dichloro-4-methylnicotinonitrile, 2,6-Dichloro-4-methylpyridine-3-carbonitrile, 3-Cyano-2,6-dichloro-4-methylpyridine
Molecular Formula:C7H4Cl2N2
Physical Properties:White to off-white crystalline powder. Molecular weight 187.03; density approx. 1.41 g/cm³ (estimated); melting point approx. 98–102 °C; boiling point approx. 318 °C (predicted); flash point approx. 145 °C (closed cup). Slightly soluble in water; soluble in methanol, ethanol, ethyl acetate, dichloromethane, DMF and other organic solvents. Relatively stable to heat and acids; hydrolysis of the cyano group or substitution of chloro groups may occur under strong alkaline conditions.
Uses:It is an important cyano-substituted pyridine intermediate widely used in pharmaceuticals, agrochemicals and fine chemical synthesis. It can be used to prepare pyridinecarboxylic acids, pyridinecarboxamides and their derivatives, and is also a key starting material for the synthesis of certain herbicides, insecticides and drug molecules. Through hydrolysis of the cyano group or functionalization at the activated chloro positions, various pyridine-containing bioactive compounds can be constructed.
Technical Specifications:
Appearance: white to off-white crystalline powder
Assay (HPLC): ≥98.0%
Melting point range: 98–102 °C
Loss on drying: ≤0.5%
Packaging: to be determined by customer consultation
