Chemical Structure

5-Amino-1-methyl-1H-1,2,3-triazole-4-carboxamide CAS 20419-66-3 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.

CATO supplies 5-Amino-1-methyl-1H-1,2,3-triazole-4-carboxamide (CAS 20419-66-3), a certified reference material (molecular formula C4H7N5O, MW 141.13 g/mol) for analytical method development and quality control.

The molecular framework of 5-Amino-1-methyl-1H-1,2,3-triazole-4-carboxamide (C4H7N5O) is characterized by 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.

As a certified reference material (CRM), 5-Amino-1-methyl-1H-1,2,3-triazole-4-carboxamide meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
