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.
Ethyl 2-(3-chloro-1H-1,2,4-triazol-1-yl)propanoate (CAS 1823967-22-1) is a high-purity analytical reference standard with the molecular formula C7H10ClN3O2 and a molecular weight of 203.63 g/mol.
The molecular framework of Ethyl 2-(3-chloro-1H-1,2,4-triazol-1-yl)propanoate (C7H10ClN3O2) is characterized by an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. 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 Ethyl 2-(3-chloro-1H-1,2,4-triazol-1-yl)propanoate 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.
