Chemical Structure
Description
8-(4,4,5,5-Tetramethyl-1,3,2-dioxaborolan-2-yl)-1-naphthonitrile (CAS 1446781-41-4), molecular formula C17H18BNO2 and molecular weight 279.14 g/mol, is a CATO reference standard with documented purity and traceability.
8-(4,4,5,5-Tetramethyl-1,3,2-dioxaborolan-2-yl)-1-naphthonitrile (C17H18BNO2) contains a steroid core, an amide 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.
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.
