5-Ethyl-1-(2-methoxy-5-methylphenyl)-1H-1,2,3-triazole-4-carboxylic acid CAS 1094373-39-3

Description

The molecular framework of 5-Ethyl-1-(2-methoxy-5-methylphenyl)-1H-1,2,3-triazole-4-carboxylic acid (C13H15N3O3) is characterized by a nitrogen-containing heterocyclic scaffold, 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

CATO supplies 5-Ethyl-1-(2-methoxy-5-methylphenyl)-1H-1,2,3-triazole-4-carboxylic acid (CAS 1094373-39-3), a certified reference material (molecular formula C13H15N3O3, MW 261.28 g/mol) for analytical method development and quality control.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
