8-Hydroxyquinoline-2-carboxamide CAS 6759-79-1

Description

The occurrence of 8-Hydroxyquinoline-2-carboxamide 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.

8-Hydroxyquinoline-2-carboxamide (CAS 6759-79-1), molecular formula C10H8N2O2 and molecular weight 188.18 g/mol, is a CATO reference standard with documented purity and traceability.

8-Hydroxyquinoline-2-carboxamide (C10H8N2O2) 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

As a certified reference material (CRM), 8-Hydroxyquinoline-2-carboxamide 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.
