3-(5-(Methylthio)-1,4-diphenyl-1H-pyrazol-3-yl)pyridine CAS 871110-02-0

Description

Compared with other compounds in its class, the molecular weight of 343.44 g/mol gives 3-(5-(Methylthio)-1,4-diphenyl-1H-pyrazol-3-yl)pyridine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

3-(5-(Methylthio)-1,4-diphenyl-1H-pyrazol-3-yl)pyridine (CAS 871110-02-0) is a high-purity analytical reference standard with the molecular formula C21H17N3S and a molecular weight of 343.44 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, 3-(5-(Methylthio)-1,4-diphenyl-1H-pyrazol-3-yl)pyridine is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 343.44 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
