Ethyl 5-(4-methoxyphenyl)-4H-1,2,4-triazole-3-carboxylate CAS 1406499-29-3

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Ethyl 5-(4-methoxyphenyl)-4H-1,2,4-triazole-3-carboxylate.

CATO supplies Ethyl 5-(4-methoxyphenyl)-4H-1,2,4-triazole-3-carboxylate (CAS 1406499-29-3), a certified reference material (molecular formula C12H13N3O3, MW 247.25 g/mol) for analytical method development and quality control.

Structurally, Ethyl 5-(4-methoxyphenyl)-4H-1,2,4-triazole-3-carboxylate (C12H13N3O3) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 247.25 g/mol, it falls into the medium-molecular-weight range. 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).

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

As a certified reference material (CRM), Ethyl 5-(4-methoxyphenyl)-4H-1,2,4-triazole-3-carboxylate 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.
