3-Allyl-4-oxo-2-phenyl-1,4-dihydroquinoline-6-carboxylic acid CAS 90033-95-7 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 305.33 g/mol gives 3-Allyl-4-oxo-2-phenyl-1,4-dihydroquinoline-6-carboxylic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

3-Allyl-4-oxo-2-phenyl-1,4-dihydroquinoline-6-carboxylic acid (CAS 90033-95-7), molecular formula C19H15NO3 and molecular weight 305.33 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, 3-Allyl-4-oxo-2-phenyl-1,4-dihydroquinoline-6-carboxylic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 305.33 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
