The occurrence of 3-{2-[(2-Fluorobenzoyl)amino]phenoxy}-2-thiophenecarboxylic acid is closely related to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
3-{2-[(2-Fluorobenzoyl)amino]phenoxy}-2-thiophenecarboxylic acid (CAS 900019-03-6), molecular formula C18H12FNO4S and molecular weight 357.36 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 3-{2-[(2-Fluorobenzoyl)amino]phenoxy}-2-thiophenecarboxylic acid (C18H12FNO4S) is characterized by a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
As a certified reference material (CRM), 3-{2-[(2-Fluorobenzoyl)amino]phenoxy}-2-thiophenecarboxylic 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.
