N-(3-Hydrazinyl-1-(4-nitrophenyl)-3-oxoprop-1-en-2-yl)benzamide CAS 19655-74-4

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including N-(3-Hydrazinyl-1-(4-nitrophenyl)-3-oxoprop-1-en-2-yl)benzamide.

N-(3-Hydrazinyl-1-(4-nitrophenyl)-3-oxoprop-1-en-2-yl)benzamide (CAS 19655-74-4) is a high-purity analytical reference standard with the molecular formula C16H14N4O4 and a molecular weight of 326.31 g/mol.

Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, N-(3-Hydrazinyl-1-(4-nitrophenyl)-3-oxoprop-1-en-2-yl)benzamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 326.31 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.
