Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 232.24 g/mol gives Ethyl 7,8-dihydro-6H-isoxazolo[5,4,3-de]quinoline-3-carboxylate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Ethyl 7,8-dihydro-6H-isoxazolo[5,4,3-de]quinoline-3-carboxylate (CAS 82419-95-2) is a high-purity analytical reference standard with the molecular formula C12H12N2O3 and a molecular weight of 232.24 g/mol.
Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, Ethyl 7,8-dihydro-6H-isoxazolo[5,4,3-de]quinoline-3-carboxylate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 232.24 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).
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), Ethyl 7,8-dihydro-6H-isoxazolo[5,4,3-de]quinoline-3-carboxylate 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.
