1-(Cyclopropylmethyl)-5-ethyl-1h-1,2,3-triazole-4-carboxylic acid (CAS 1250363-89-3) is a high-purity analytical reference standard with the molecular formula C9H13N3O2 and a molecular weight of 195.22 g/mol.
1-(Cyclopropylmethyl)-5-ethyl-1h-1,2,3-triazole-4-carboxylic acid (C9H13N3O2) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
