Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 173.17 g/mol gives 8-Hydroxyquinoline-6-carbaldehyde distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 8-Hydroxyquinoline-6-carbaldehyde (CAS 343856-49-5), a certified reference material (molecular formula C10H7NO2, MW 173.17 g/mol) for analytical method development and quality control.
8-Hydroxyquinoline-6-carbaldehyde (C10H7NO2) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
