1-Cyclopropyl-5-(2-hydroxy-5-methylbenzoyl)-2-oxo-1,2-dihydropyridine-3-carbonitrile CAS 554407-87-3

Description

1-Cyclopropyl-5-(2-hydroxy-5-methylbenzoyl)-2-oxo-1,2-dihydropyridine-3-carbonitrile (CAS 554407-87-3) is a high-purity analytical reference standard with the molecular formula C17H14N2O3 and a molecular weight of 294.30 g/mol.

Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, 1-Cyclopropyl-5-(2-hydroxy-5-methylbenzoyl)-2-oxo-1,2-dihydropyridine-3-carbonitrile is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 294.30 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.
