Chemical Structure
Description
7-Fluoro-2-[(4-fluoroanilino)methylene]-3-phenyl-1-indanone (CAS 339115-72-9) is a high-purity analytical reference standard with the molecular formula C22H15F2NO and a molecular weight of 347.36 g/mol.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution, 7-Fluoro-2-[(4-fluoroanilino)methylene]-3-phenyl-1-indanone is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 347.36 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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), 7-Fluoro-2-[(4-fluoroanilino)methylene]-3-phenyl-1-indanone 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.
