Chemical Structure

1,2,4-Triazolo[4,3-b]pyridazine CAS 274-83-9 chemical structure

Description

CATO manufactures 1,2,4-Triazolo[4,3-b]pyridazine 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.

1,2,4-Triazolo[4,3-b]pyridazine (CAS 274-83-9) is a high-purity analytical reference standard with the molecular formula C5H4N4 and a molecular weight of 120.11 g/mol.

The molecular framework of 1,2,4-Triazolo[4,3-b]pyridazine (C5H4N4) is characterized by a nitrile group. 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 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.
