Chemical Structure
Description
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.
3-Acetyl-2-methylquinolin-4(1H)-one (CAS 86769-09-7), molecular formula C12H11NO2 and molecular weight 201.22 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, 3-Acetyl-2-methylquinolin-4(1H)-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 201.22 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.
