Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
4,4,5,5-Tetramethyl-2-{4-[(3-methylphenyl)methoxy]phenyl}-1,3,2-dioxaborolane (CAS 1029439-14-2), molecular formula C20H25BO3 and molecular weight 324.22 g/mol, is a CATO reference standard with documented purity and traceability.
4,4,5,5-Tetramethyl-2-{4-[(3-methylphenyl)methoxy]phenyl}-1,3,2-dioxaborolane (C20H25BO3) 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.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
