Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
5-methyl-1-(pyridin-4-ylmethyl)-1H-1,2,3-triazole-4-carboxylic acid hydrochloride (CAS 1803601-84-4), molecular formula C10H10N4O2HCl and molecular weight 254.67 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 5-methyl-1-(pyridin-4-ylmethyl)-1H-1,2,3-triazole-4-carboxylic acid hydrochloride (C10H10N4O2HCl) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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), 5-methyl-1-(pyridin-4-ylmethyl)-1H-1,2,3-triazole-4-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.
