Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 172.98 g/mol gives Quinoline-7-boronic Acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Quinoline-7-boronic Acid (CAS 629644-82-2), molecular formula C9H8BNO2 and molecular weight 172.98 g/mol, is a CATO reference standard with documented purity and traceability.
Quinoline-7-boronic Acid (C9H8BNO2) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. 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.
