Description
As a certified reference material (CRM), 4-chloro-1H-Imidazo[4,5-c]pyridine 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.
4-chloro-1H-Imidazo[4,5-c]pyridine (CAS 2770-01-6), molecular formula C6H4ClN3 and molecular weight 153.57 g/mol, is a CATO reference standard with documented purity and traceability.
4-chloro-1H-Imidazo[4,5-c]pyridine (C6H4ClN3) 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
