Chemical Structure
Description
4053-38-7 Quinoline, 8-methyl-, 1-oxide (CAS 4053-38-7), molecular formula C10H9NO and molecular weight 159.18 g/mol, is a CATO reference standard with documented purity and traceability.
4053-38-7 Quinoline, 8-methyl-, 1-oxide (C10H9NO) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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).
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.
