The occurrence of 2-(3-tert-Butyl-4-methoxymethoxy-phenyl)-4,4,5,5-tetramethyl-[1,3,2]dioxaborolane is closely related to a steroid core, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2-(3-tert-Butyl-4-methoxymethoxy-phenyl)-4,4,5,5-tetramethyl-[1,3,2]dioxaborolane (CAS 1442430-86-5), molecular formula C18H29BO4 and molecular weight 320.23 g/mol, is a CATO reference standard with documented purity and traceability.
2-(3-tert-Butyl-4-methoxymethoxy-phenyl)-4,4,5,5-tetramethyl-[1,3,2]dioxaborolane (C18H29BO4) 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 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.
