Description
As a certified reference material (CRM), 2-Chloro-5-iodo-3-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.
2-Chloro-5-iodo-3-methylpyridine (CAS 59782-89-7), molecular formula C6H5ClIN and molecular weight 253.47 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrile group, chlorine/iodine substitution, an aromatic ring system, 2-Chloro-5-iodo-3-methylpyridine is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 253.47 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
