Chemical Structure
Description
The molecular framework of 2-Fluoro-4-propylbenzoic acid (C10H11FO2) 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.
2-Fluoro-4-propylbenzoic acid (CAS 182116-30-9), molecular formula C10H11FO2 and molecular weight 182.19 g/mol, is a CATO reference standard with documented purity and traceability.
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), 2-Fluoro-4-propylbenzoic 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.
