Chemical Structure

1-Ethyl-1,2,4-triazole CAS 16778-70-4 chemical structure

Description

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

1-Ethyl-1,2,4-triazole (CAS 16778-70-4) is a high-purity analytical reference standard with the molecular formula C4H7N3 and a molecular weight of 97.12 g/mol.

Owing to a nitrile group, 1-Ethyl-1,2,4-triazole is typically white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 97.12 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.

CATO manufactures 1-Ethyl-1,2,4-triazole 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.
