1-(3-Nitrophenyl)-4-(p-tolyl)-1H-pyrazol-5-amine CAS 242797-18-8

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-(3-Nitrophenyl)-4-(p-tolyl)-1H-pyrazol-5-amine.

CATO supplies 1-(3-Nitrophenyl)-4-(p-tolyl)-1H-pyrazol-5-amine (CAS 242797-18-8), a certified reference material (molecular formula C16H14N4O2, MW 294.31 g/mol) for analytical method development and quality control.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 1-(3-Nitrophenyl)-4-(p-tolyl)-1H-pyrazol-5-amine is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 294.31 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
