Chemical Structure
Description
86-58-8 5QS1A25IJ6 8-Quinolineboronic acid UNII-5QS1A25IJ6 8-Quinolineboronic acid [MI] Boronic acid, B-8-quinolinyl- (Quinolin-8-yl)boronic acid 8-Quinolinylboronic acid 8-Quinolylboronic acid (C9H18BNO2) 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
86-58-8 5QS1A25IJ6 8-Quinolineboronic acid UNII-5QS1A25IJ6 8-Quinolineboronic acid [MI] Boronic acid, B-8-quinolinyl- (Quinolin-8-yl)boronic acid 8-Quinolinylboronic acid 8-Quinolylboronic acid (CAS 86-58-8), molecular formula C9H18BNO2 and molecular weight 183.06 g/mol, is a CATO reference standard with documented purity and traceability.
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.
