Chemical Structure

4,5-Dichloro-2-propylpyridazin-3(2H)-one CAS 51659-95-1 chemical structure

Description

CATO manufactures 4,5-Dichloro-2-propylpyridazin-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.

CATO supplies 4,5-Dichloro-2-propylpyridazin-3(2H)-one (CAS 51659-95-1), a certified reference material (molecular formula C7H8Cl2N2O, MW 207.06 g/mol) for analytical method development and quality control.

Structurally, 4,5-Dichloro-2-propylpyridazin-3(2H)-one (C7H8Cl2N2O) contains an amide group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 207.06 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).

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.
