(3-chloro-5-pyridyl)boronic acid 3-chloropyridine-5-boronic acid 5-chloro-3-pyridineboronic acid 5-chloro-3-pyridinyl boronic acid 5-chloropyridin-3-yl-3-boronic acid 5-chloropyridin-3-ylboronic acid 5-chloropyridine-3-boronic acid 5-chloropyridne-3-boronic acid 872041-85-5 (CAS 872041-85-5) is a high-purity analytical reference standard with the molecular formula C5H11BClNO2 and a molecular weight of 163.41 g/mol.
Structurally, (3-chloro-5-pyridyl)boronic acid 3-chloropyridine-5-boronic acid 5-chloro-3-pyridineboronic acid 5-chloro-3-pyridinyl boronic acid 5-chloropyridin-3-yl-3-boronic acid 5-chloropyridin-3-ylboronic acid 5-chloropyridine-3-boronic acid 5-chloropyridne-3-boronic acid 872041-85-5 (C5H11BClNO2) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 0.5, corresponding to approximately 0 ring(s) or double-bond equivalent(s). With a molecular weight of 163.41 g/mol, it falls into the medium-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
