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-Bis(3-fluorobenzyl)pentane-2,4-dione.
3,3-Bis(3-fluorobenzyl)pentane-2,4-dione (CAS 477847-91-9) is a high-purity analytical reference standard with the molecular formula C19H18F2O2 and a molecular weight of 316.34 g/mol.
3,3-Bis(3-fluorobenzyl)pentane-2,4-dione (C19H18F2O2) contains a steroid core, a hydroxyl group, an ether linkage, fluorine substitution. Halogen substitution raises its density and boiling point, 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.
CATO manufactures 3,3-Bis(3-fluorobenzyl)pentane-2,4-dione under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
