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 {1-methyl-5-[(4-methylphenyl)sulfanyl]-3-phenyl-1H-pyrazol-4-yl}methyl N-phenylcarbamate (CAS 318247-44-8), a certified reference material (molecular formula C25H23N3O2S, MW 429.53 g/mol) for analytical method development and quality control.
The molecular framework of {1-methyl-5-[(4-methylphenyl)sulfanyl]-3-phenyl-1H-pyrazol-4-yl}methyl N-phenylcarbamate (C25H23N3O2S) 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. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
