Chemical Structure
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.
CATO supplies 4-[3-Nitro-4-(4-phenylpiperazin-1-yl)phenyl]-1,2-dihydrophthalazin-1-one (CAS 882000-44-4), a certified reference material (molecular formula C24H21N5O3, MW 427.46 g/mol) for analytical method development and quality control.
Based on its molecular formula C24H21N5O3, 4-[3-Nitro-4-(4-phenylpiperazin-1-yl)phenyl]-1,2-dihydrophthalazin-1-one contains a steroid core, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 427.46 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
