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-methyl-4-(thiophen-2-yl)-5,6,7,8-tetrahydro-1,6-naphthyridin-2-yl)thio)-N-(3,4-dimethoxyphenyl)acetamide.

2-((3-Cyano-6-methyl-4-(thiophen-2-yl)-5,6,7,8-tetrahydro-1,6-naphthyridin-2-yl)thio)-N-(3,4-dimethoxyphenyl)acetamide (CAS 496018-61-2) is a high-purity analytical reference standard with the molecular formula C24H24N4O3S2 and a molecular weight of 480.60 g/mol.

Structurally, 2-((3-Cyano-6-methyl-4-(thiophen-2-yl)-5,6,7,8-tetrahydro-1,6-naphthyridin-2-yl)thio)-N-(3,4-dimethoxyphenyl)acetamide (C24H24N4O3S2) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 15.0, corresponding to approximately 15 ring(s) or double-bond equivalent(s). With a molecular weight of 480.60 g/mol, it falls into the moderately-high-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
