Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
4,4,4-Trifluoro-1-(2-methoxyphenyl)butane-1,3-dione (CAS 15191-69-2) is a high-purity analytical reference standard with the molecular formula C11H9F3O3 and a molecular weight of 246.18 g/mol.
The molecular framework of 4,4,4-Trifluoro-1-(2-methoxyphenyl)butane-1,3-dione (C11H9F3O3) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
As a certified reference material (CRM), 4,4,4-Trifluoro-1-(2-methoxyphenyl)butane-1,3-dione 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.
