Chemical Structure
Description
4-Chloro-3-(chloromethyl)-5-methylpyridine (CAS 1393563-00-2) is a high-purity analytical reference standard with the molecular formula C7H7Cl2N and a molecular weight of 176.04 g/mol.
4-Chloro-3-(chloromethyl)-5-methylpyridine (C7H7Cl2N) contains a nitrile group, chlorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 4-Chloro-3-(chloromethyl)-5-methylpyridine meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
