Description
Compared with other compounds in its class, the molecular weight of 356.27 g/mol gives 1,3-Bis(3-(difluoromethoxy)phenyl)propane-1,3-dione distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
1,3-Bis(3-(difluoromethoxy)phenyl)propane-1,3-dione (CAS 938004-15-0) is a high-purity analytical reference standard with the molecular formula C17H12F4O4 and a molecular weight of 356.27 g/mol.
The molecular framework of 1,3-Bis(3-(difluoromethoxy)phenyl)propane-1,3-dione (C17H12F4O4) is characterized by a flavonoid core, a hydroxyl group, an ether linkage, fluorine substitution. 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.
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), 1,3-Bis(3-(difluoromethoxy)phenyl)propane-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.
