Description
As a certified reference material (CRM), Pyridin-2(1H)-one 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.
CATO supplies Pyridin-2(1H)-one hydrochloride (CAS 13472-62-3), a certified reference material (molecular formula C5H5NOHCl, MW 131.56 g/mol) for analytical method development and quality control.
Pyridin-2(1H)-one hydrochloride (C5H5NOHCl) 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
