Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 4-chloro-1-methyl-pyrazolo[4,3-c]pyridine-6-carbonyl chloride (CAS 2633010-65-6), a certified reference material (molecular formula C8H13Cl2N3O, MW 238.11 g/mol) for analytical method development and quality control.
4-chloro-1-methyl-pyrazolo[4,3-c]pyridine-6-carbonyl chloride (C8H13Cl2N3O) 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), 4-chloro-1-methyl-pyrazolo[4,3-c]pyridine-6-carbonyl chloride 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.
