Chemical Structure

(2E,5E)-2,5-Bis[(2-fluorophenyl)methylidene]cyclopentan-1-one CAS 1158188-88-5 chemical structure

Description

The occurrence of (2E,5E)-2,5-Bis[(2-fluorophenyl)methylidene]cyclopentan-1-one is closely related to a steroid core, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies (2E,5E)-2,5-Bis[(2-fluorophenyl)methylidene]cyclopentan-1-one (CAS 1158188-88-5), a certified reference material (molecular formula C19H14F2O, MW 296.31 g/mol) for analytical method development and quality control.

(2E,5E)-2,5-Bis[(2-fluorophenyl)methylidene]cyclopentan-1-one (C19H14F2O) 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; 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 (2E,5E)-2,5-Bis[(2-fluorophenyl)methylidene]cyclopentan-1-one 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.
