Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3,3'-(9H-fluorene-9,9-diyl)dipropionic acid.
3,3'-(9H-fluorene-9,9-diyl)dipropionic acid (CAS 4425-95-0) is a high-purity analytical reference standard with the molecular formula C19H18O4 and a molecular weight of 310.34 g/mol.
3,3'-(9H-fluorene-9,9-diyl)dipropionic acid (C19H18O4) contains a flavonoid 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), 3,3'-(9H-fluorene-9,9-diyl)dipropionic 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.
