Description
As a certified reference material (CRM), 1-(2-Chlorobenzyl)-5-methoxy-1H-1,2,3-triazole-4-carboxylic acid 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.
1-(2-Chlorobenzyl)-5-methoxy-1H-1,2,3-triazole-4-carboxylic acid (CAS 1378258-91-3), molecular formula C11H10ClN3O3 and molecular weight 267.67 g/mol, is a CATO reference standard with documented purity and traceability.
1-(2-Chlorobenzyl)-5-methoxy-1H-1,2,3-triazole-4-carboxylic acid (C11H10ClN3O3) contains a nitrogen-containing heterocyclic scaffold, an amide 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. 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.
