3-(4-fluorophenyl)but-2-enoic acid CAS 1201-86-1

Description

The occurrence of 3-(4-fluorophenyl)but-2-enoic acid is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

3-(4-fluorophenyl)but-2-enoic acid (CAS 1201-86-1) is a high-purity analytical reference standard with the molecular formula C10H9FO2 and a molecular weight of 180.18 g/mol.

3-(4-fluorophenyl)but-2-enoic acid (C10H9FO2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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-(4-fluorophenyl)but-2-enoic 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.
