CATO supplies 18772-76-4 3-(p-Anisyl)-6-hydrazinopyridazine 3-Hydrazino-6-(p-methoxyphenyl)-pyridazine 3-Hydrazinyl-6-(4-methoxyphenyl)-pyridazine SKF 91957 (CAS 18772-76-4), a certified reference material (molecular formula C11H12N4O, MW 216.24 g/mol) for analytical method development and quality control.
The molecular framework of 18772-76-4 3-(p-Anisyl)-6-hydrazinopyridazine 3-Hydrazino-6-(p-methoxyphenyl)-pyridazine 3-Hydrazinyl-6-(4-methoxyphenyl)-pyridazine SKF 91957 (C11H12N4O) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. 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.
