Chemical Structure

3-{4h,5h,6h-cyclopenta[b]thiophen-2-yl}-4-methyl-1-phenyl-1h-pyrazol-5-amine CAS 1152923-93-7 chemical structure

Description

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

CATO supplies 3-{4h,5h,6h-cyclopenta[b]thiophen-2-yl}-4-methyl-1-phenyl-1h-pyrazol-5-amine (CAS 1152923-93-7), a certified reference material (molecular formula C17H17N3S, MW 295.40 g/mol) for analytical method development and quality control.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, 3-{4h,5h,6h-cyclopenta[b]thiophen-2-yl}-4-methyl-1-phenyl-1h-pyrazol-5-amine is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 295.40 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
