Chemical Structure

5,6-Dihydro-1H-[1,3]oxazino[5,4,3-ij]quinoline-3,7-dione CAS 112646-14-7 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 203.19 g/mol gives 5,6-Dihydro-1H-[1,3]oxazino[5,4,3-ij]quinoline-3,7-dione distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

5,6-Dihydro-1H-[1,3]oxazino[5,4,3-ij]quinoline-3,7-dione (CAS 112646-14-7), molecular formula C11H9NO3 and molecular weight 203.19 g/mol, is a CATO reference standard with documented purity and traceability.

5,6-Dihydro-1H-[1,3]oxazino[5,4,3-ij]quinoline-3,7-dione (C11H9NO3) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

As a certified reference material (CRM), 5,6-Dihydro-1H-[1,3]oxazino[5,4,3-ij]quinoline-3,7-dione 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.
