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.
3-Hydroxy-2,3-dimethylbutan-2-yl hydrogen (4-(4-methylpiperidin-1-yl)thiophen-2-yl)boronate (CAS 2223031-88-5), molecular formula C16H28BNO3S and molecular weight 325.27 g/mol, is a CATO reference standard with documented purity and traceability.
3-Hydroxy-2,3-dimethylbutan-2-yl hydrogen (4-(4-methylpiperidin-1-yl)thiophen-2-yl)boronate (C16H28BNO3S) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
