Chemical Structure
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-Cyclopropyl-1-(2-methoxyethyl)-1h-1,2,3-triazole-4-carboxylic acid (CAS 1251135-04-2), molecular formula C9H13N3O3 and molecular weight 211.22 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 5-Cyclopropyl-1-(2-methoxyethyl)-1h-1,2,3-triazole-4-carboxylic acid (C9H13N3O3) is characterized by an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. 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. 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).
CATO manufactures 5-Cyclopropyl-1-(2-methoxyethyl)-1h-1,2,3-triazole-4-carboxylic acid under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
