Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-ACetoxy-2,3,5,6-tetrafluorobenzoic acid methyl ester.
4-ACetoxy-2,3,5,6-tetrafluorobenzoic acid methyl ester (CAS 786-52-7) is a high-purity analytical reference standard with the molecular formula C10H6F4O4 and a molecular weight of 266.15 g/mol.
The molecular framework of 4-ACetoxy-2,3,5,6-tetrafluorobenzoic acid methyl ester (C10H6F4O4) 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.
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), 4-ACetoxy-2,3,5,6-tetrafluorobenzoic acid methyl ester 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.
