6,6-dimethyl-2-oxo-1,2,5,6,7,8-hexahydroquinoline-3-carboxylic acid CAS 1342675-19-7

Description

The occurrence of 6,6-dimethyl-2-oxo-1,2,5,6,7,8-hexahydroquinoline-3-carboxylic acid is closely related to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

6,6-dimethyl-2-oxo-1,2,5,6,7,8-hexahydroquinoline-3-carboxylic acid (CAS 1342675-19-7), molecular formula C12H15NO3 and molecular weight 221.25 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 6,6-dimethyl-2-oxo-1,2,5,6,7,8-hexahydroquinoline-3-carboxylic acid (C12H15NO3) is characterized by an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
