Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 384.50 g/mol gives 2,5-Dimethyl-1-{2-[6-(4-methylphenyl)pyrazolo[1,5-a]pyrimidin-2-yl]thiophen-3-yl}-1H-pyrrole distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 2,5-Dimethyl-1-{2-[6-(4-methylphenyl)pyrazolo[1,5-a]pyrimidin-2-yl]thiophen-3-yl}-1H-pyrrole (CAS 691884-05-6), a certified reference material (molecular formula C23H20N4S, MW 384.50 g/mol) for analytical method development and quality control.
The molecular framework of 2,5-Dimethyl-1-{2-[6-(4-methylphenyl)pyrazolo[1,5-a]pyrimidin-2-yl]thiophen-3-yl}-1H-pyrrole (C23H20N4S) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
