1-Methyl-2-oxo-1,2-dihydroquinoline-3-carboxylic acid CAS 67984-94-5

Description

The occurrence of 1-Methyl-2-oxo-1,2-dihydroquinoline-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.

1-Methyl-2-oxo-1,2-dihydroquinoline-3-carboxylic acid (CAS 67984-94-5), molecular formula C11H9NO3 and molecular weight 203.19 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, 1-Methyl-2-oxo-1,2-dihydroquinoline-3-carboxylic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 203.19 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.

As a certified reference material (CRM), 1-Methyl-2-oxo-1,2-dihydroquinoline-3-carboxylic acid meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
