Description
As a certified reference material (CRM), 4-(Chloromethyl)-3,5-dichloropyridine 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.
CATO supplies 4-(Chloromethyl)-3,5-dichloropyridine (CAS 264123-70-8), a certified reference material (molecular formula C6H4Cl3N, MW 196.46 g/mol) for analytical method development and quality control.
Owing to a nitrile group, chlorine substitution, an aromatic ring system, 4-(Chloromethyl)-3,5-dichloropyridine is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 196.46 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
