Chemical Structure
Description
2-(3-Butoxy-5-methylphenyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (C17H27BO3) contains a steroid core, 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
2-(3-Butoxy-5-methylphenyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (CAS 1218789-82-2), molecular formula C17H27BO3 and molecular weight 290.21 g/mol, is a CATO reference standard with documented purity and traceability.
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.
