1-(Methylsulfonyl)-5-(thiophen-2-yl)-3-(p-tolyl)-4,5-dihydro-1H-pyrazole CAS 497247-32-2

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-(Methylsulfonyl)-5-(thiophen-2-yl)-3-(p-tolyl)-4,5-dihydro-1H-pyrazole.

CATO supplies 1-(Methylsulfonyl)-5-(thiophen-2-yl)-3-(p-tolyl)-4,5-dihydro-1H-pyrazole (CAS 497247-32-2), a certified reference material (molecular formula C15H16N2O2S2, MW 320.43 g/mol) for analytical method development and quality control.

Structurally, 1-(Methylsulfonyl)-5-(thiophen-2-yl)-3-(p-tolyl)-4,5-dihydro-1H-pyrazole (C15H16N2O2S2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 320.43 g/mol, it falls into the moderately-high-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
