Description

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

4-Bromo-5-((2,4-difluorophenyl)amino)-2-(2-oxopropyl)pyridazin-3(2H)-one (CAS 477860-36-9), molecular formula C13H10BrF2N3O2 and molecular weight 358.14 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 4-Bromo-5-((2,4-difluorophenyl)amino)-2-(2-oxopropyl)pyridazin-3(2H)-one (C13H10BrF2N3O2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 358.14 g/mol, it falls into the moderately-high-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).

CATO manufactures 4-Bromo-5-((2,4-difluorophenyl)amino)-2-(2-oxopropyl)pyridazin-3(2H)-one 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.
