Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 9,9-Diphenyl-9H-fluorene-4-boronic Acid.
CATO supplies 9,9-Diphenyl-9H-fluorene-4-boronic Acid (CAS 1224976-40-2), a certified reference material (molecular formula C25H19BO2, MW 362.23 g/mol) for analytical method development and quality control.
9,9-Diphenyl-9H-fluorene-4-boronic Acid (C25H19BO2) 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
