Chemical Structure
Description
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.
2-(4,4,5,5-Tetramethyl-1,3,2-dioxaborolan-2-yl)pyridin-3-amine (CAS 948593-70-2) is a high-purity analytical reference standard with the molecular formula C11H17BN2O2 and a molecular weight of 220.08 g/mol.
Based on its molecular formula C11H17BN2O2, 2-(4,4,5,5-Tetramethyl-1,3,2-dioxaborolan-2-yl)pyridin-3-amine contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 220.08 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
