Chemical Structure
Description
Owing to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, (2Z)-2-(4-Methylbenzenesulfonyl)-3-[3-(naphthalen-2-yl)-1-phenyl-1H-pyrazol-4-yl]prop-2-enenitrile is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 475.56 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
CATO supplies (2Z)-2-(4-Methylbenzenesulfonyl)-3-[3-(naphthalen-2-yl)-1-phenyl-1H-pyrazol-4-yl]prop-2-enenitrile (CAS 957042-53-4), a certified reference material (molecular formula C29H21N3O2S, MW 475.56 g/mol) for analytical method development and quality control.
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.
