(1,3-diphenyl-1H-pyrazol-4-yl)(piperidin-1-yl)methanethione CAS 312746-22-8

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (1,3-diphenyl-1H-pyrazol-4-yl)(piperidin-1-yl)methanethione.

CATO supplies (1,3-diphenyl-1H-pyrazol-4-yl)(piperidin-1-yl)methanethione (CAS 312746-22-8), a certified reference material (molecular formula C21H21N3S, MW 347.48 g/mol) for analytical method development and quality control.

Based on its molecular formula C21H21N3S, (1,3-diphenyl-1H-pyrazol-4-yl)(piperidin-1-yl)methanethione contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 347.48 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
