7-Ethoxy-4,5-dihydroisoxazolo[5,4-f]quinoline CAS 135219-97-5 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 216.24 g/mol gives 7-Ethoxy-4,5-dihydroisoxazolo[5,4-f]quinoline distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

7-Ethoxy-4,5-dihydroisoxazolo[5,4-f]quinoline (CAS 135219-97-5), molecular formula C12H12N2O2 and molecular weight 216.24 g/mol, is a CATO reference standard with documented purity and traceability.

7-Ethoxy-4,5-dihydroisoxazolo[5,4-f]quinoline (C12H12N2O2) 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 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.

As a certified reference material (CRM), 7-Ethoxy-4,5-dihydroisoxazolo[5,4-f]quinoline 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.
