Chemical Structure
Description
As a certified reference material (CRM), pyridazine-3-carboxylic acid;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 pyridazine-3-carboxylic acid;hydrochloride (CAS 674783-27-8), a certified reference material (molecular formula C5H10N2O2HCl, MW 166.60 g/mol) for analytical method development and quality control.
pyridazine-3-carboxylic acid;hydrochloride (C5H10N2O2HCl) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; 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.
