Chemical Structure
Description
The occurrence of 5-(2-(Bis(4-(dimethylamino)phenyl)methylene)hydrazinyl)-4-chloropyridazin-3(2H)-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.
5-(2-(Bis(4-(dimethylamino)phenyl)methylene)hydrazinyl)-4-chloropyridazin-3(2H)-one (CAS 6954-15-0), molecular formula C21H23ClN6O and molecular weight 410.90 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 5-(2-(Bis(4-(dimethylamino)phenyl)methylene)hydrazinyl)-4-chloropyridazin-3(2H)-one (C21H23ClN6O) 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
