Chemical Structure
Description
The occurrence of 4-methyl-4H-1,2,4-triazole-3-carboxylic acid is closely related to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 4-methyl-4H-1,2,4-triazole-3-carboxylic acid (CAS 944897-40-9), a certified reference material (molecular formula C4H9N3O2, MW 131.13 g/mol) for analytical method development and quality control.
The molecular framework of 4-methyl-4H-1,2,4-triazole-3-carboxylic acid (C4H9N3O2) 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
