2-(4-Octylphenyl)-4-oxo-1,4-dihydroquinoline-8-carboxylic acid CAS 90034-80-3

Description

The occurrence of 2-(4-Octylphenyl)-4-oxo-1,4-dihydroquinoline-8-carboxylic acid is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

2-(4-Octylphenyl)-4-oxo-1,4-dihydroquinoline-8-carboxylic acid (CAS 90034-80-3), molecular formula C24H27NO3 and molecular weight 377.48 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, 2-(4-Octylphenyl)-4-oxo-1,4-dihydroquinoline-8-carboxylic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 377.48 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
