Chemical Structure
Description
The molecular framework of 4-(4-Fluorobenzoyl)isophthalic Acid (C15H9FO5) is characterized by a flavonoid core, a hydroxyl group, an ether linkage, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
4-(4-Fluorobenzoyl)isophthalic Acid (CAS 1645-24-5) is a high-purity analytical reference standard with the molecular formula C15H9FO5 and a molecular weight of 288.23 g/mol.
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), 4-(4-Fluorobenzoyl)isophthalic Acid 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.
