Chemical Structure
Description
Based on its molecular formula C12H17BO4, (4-(2-(tert-Butoxy)-2-oxoethyl)phenyl)boronic acid contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 236.07 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.
CATO supplies (4-(2-(tert-Butoxy)-2-oxoethyl)phenyl)boronic acid (CAS 1133749-58-2), a certified reference material (molecular formula C12H17BO4, MW 236.07 g/mol) for analytical method development and quality control.
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.
