1-(Thiophen-2-yl)-1H-pyrazole CAS 74990-30-0

Description

Compared with other compounds in its class, the molecular weight of 150.20 g/mol gives 1-(Thiophen-2-yl)-1H-pyrazole distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 1-(Thiophen-2-yl)-1H-pyrazole (CAS 74990-30-0), a certified reference material (molecular formula C7H6N2S, MW 150.20 g/mol) for analytical method development and quality control.

Owing to a nitrile group, sulfur-containing functionality, an aromatic ring system, 1-(Thiophen-2-yl)-1H-pyrazole is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 150.20 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

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.
