Chemical Structure
Description
The occurrence of 4,4,5,5-Tetramethyl-2-(9-phenyldibenzo[b,d]furan-3-yl)-1,3,2-dioxaborane 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.
4,4,5,5-Tetramethyl-2-(9-phenyldibenzo[b,d]furan-3-yl)-1,3,2-dioxaborane (CAS 2360830-98-2), molecular formula C24H23BO3 and molecular weight 370.25 g/mol, is a CATO reference standard with documented purity and traceability.
4,4,5,5-Tetramethyl-2-(9-phenyldibenzo[b,d]furan-3-yl)-1,3,2-dioxaborane (C24H23BO3) 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.
As a certified reference material (CRM), 4,4,5,5-Tetramethyl-2-(9-phenyldibenzo[b,d]furan-3-yl)-1,3,2-dioxaborane meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
