Chemical Structure
Description
4-(2-Phenyl-6-((phenylsulfinyl)methyl)pyrimidin-4-yl)morpholine (CAS 320421-35-0) is a high-purity analytical reference standard with the molecular formula C21H21N3O2S and a molecular weight of 379.48 g/mol.
The molecular framework of 4-(2-Phenyl-6-((phenylsulfinyl)methyl)pyrimidin-4-yl)morpholine (C21H21N3O2S) is characterized by a steroid core, an amide group, a sulfone 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.
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.
