CATO supplies 1-(2-Chlorobenzyl)-5-methyl-1h-1,2,3-triazole-4-carboxylic acid (CAS 1034738-41-4), a certified reference material (molecular formula C11H10ClN3O2, MW 251.67 g/mol) for analytical method development and quality control.
1-(2-Chlorobenzyl)-5-methyl-1h-1,2,3-triazole-4-carboxylic acid (C11H10ClN3O2) 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. 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.
