Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
3-Chloro-4-methoxypyridine hydrochloride (CAS 861024-97-7), molecular formula C6H6ClNOHCl and molecular weight 180.03 g/mol, is a CATO reference standard with documented purity and traceability.
3-Chloro-4-methoxypyridine hydrochloride (C6H6ClNOHCl) contains an amide group, a hydroxyl group, an ether linkage, chlorine substitution. 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.
As a certified reference material (CRM), 3-Chloro-4-methoxypyridine hydrochloride 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.
