(2-chloro-3-quinolinyl)boronic acid(saltdata: free) (2-chloroquinolin-3-yl)boronic acid 128676-84-6 2 - Chloro - 3 - quinolineboronic acid 2-Chloroquinoline-3-boronic acid 2-chloro-3-quinoline boronic acid 2-chloro-3-quinolyl boronic acid 3-borono-2-chloroquinoline akos brn-0209 boronic acid, (2-chloro-3-quinolinyl)- (CAS 128676-84-6) is a high-purity analytical reference standard with the molecular formula C9H7BClNO2 and a molecular weight of 207.42 g/mol.
Based on its molecular formula C9H7BClNO2, (2-chloro-3-quinolinyl)boronic acid(saltdata: free) (2-chloroquinolin-3-yl)boronic acid 128676-84-6 2 - Chloro - 3 - quinolineboronic acid 2-Chloroquinoline-3-boronic acid 2-chloro-3-quinoline boronic acid 2-chloro-3-quinolyl boronic acid 3-borono-2-chloroquinoline akos brn-0209 boronic acid, (2-chloro-3-quinolinyl)- contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 207.42 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
