9-hydroxy-2,3-dihydro[1,4]dioxino[2,3-g]quinoline-8-carboxylic acid CAS 23796-64-7

Description

The occurrence of 9-hydroxy-2,3-dihydro[1,4]dioxino[2,3-g]quinoline-8-carboxylic acid is closely related to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

9-hydroxy-2,3-dihydro[1,4]dioxino[2,3-g]quinoline-8-carboxylic acid (CAS 23796-64-7), molecular formula C12H9NO5 and molecular weight 247.20 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, 9-hydroxy-2,3-dihydro[1,4]dioxino[2,3-g]quinoline-8-carboxylic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 247.20 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), 9-hydroxy-2,3-dihydro[1,4]dioxino[2,3-g]quinoline-8-carboxylic acid 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.
