(1E,4E)-1-(2-{6-[(2,4-dichlorophenyl)methyl]pyridazin-3-yl}hydrazin-1-yl)-5-phenylpenta-1,4-dien-3-one CAS 860649-39-4 chemical structure

Description

The occurrence of (1E,4E)-1-(2-{6-[(2,4-dichlorophenyl)methyl]pyridazin-3-yl}hydrazin-1-yl)-5-phenylpenta-1,4-dien-3-one is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

(1E,4E)-1-(2-{6-[(2,4-dichlorophenyl)methyl]pyridazin-3-yl}hydrazin-1-yl)-5-phenylpenta-1,4-dien-3-one (CAS 860649-39-4) is a high-purity analytical reference standard with the molecular formula C22H18Cl2N4O and a molecular weight of 425.31 g/mol.

The molecular framework of (1E,4E)-1-(2-{6-[(2,4-dichlorophenyl)methyl]pyridazin-3-yl}hydrazin-1-yl)-5-phenylpenta-1,4-dien-3-one (C22H18Cl2N4O) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. 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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
