2-((3-Cyano-6-(4-methoxyphenyl)-4-phenylpyridin-2-yl)thio)-N-(2-methyl-5-nitrophenyl)acetamide CAS 332175-65-2

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-((3-Cyano-6-(4-methoxyphenyl)-4-phenylpyridin-2-yl)thio)-N-(2-methyl-5-nitrophenyl)acetamide.

2-((3-Cyano-6-(4-methoxyphenyl)-4-phenylpyridin-2-yl)thio)-N-(2-methyl-5-nitrophenyl)acetamide (CAS 332175-65-2) is a high-purity analytical reference standard with the molecular formula C28H22N4O4S and a molecular weight of 510.56 g/mol.

Owing to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, 2-((3-Cyano-6-(4-methoxyphenyl)-4-phenylpyridin-2-yl)thio)-N-(2-methyl-5-nitrophenyl)acetamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 510.56 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).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

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.
