Chemical Structure
Description
The occurrence of (9,9-Dimethyl-9H-fluoren-1-yl)boronic acid is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
(9,9-Dimethyl-9H-fluoren-1-yl)boronic acid (CAS 1251825-71-4), molecular formula C15H15BO2 and molecular weight 238.09 g/mol, is a CATO reference standard with documented purity and traceability.
(9,9-Dimethyl-9H-fluoren-1-yl)boronic acid (C15H15BO2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. 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).
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), (9,9-Dimethyl-9H-fluoren-1-yl)boronic acid 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.
