5-(Thiophen-2-yl)-1-(p-tolyl)-1H-pyrazole CAS 1269291-68-0

Description

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, 5-(Thiophen-2-yl)-1-(p-tolyl)-1H-pyrazole is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 240.32 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.

5-(Thiophen-2-yl)-1-(p-tolyl)-1H-pyrazole (CAS 1269291-68-0) is a high-purity analytical reference standard with the molecular formula C14H12N2S and a molecular weight of 240.32 g/mol.

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.
