Description

As a certified reference material (CRM), (3-Fluoro-4-hydroxy-phenyl)-acetic acid 3-Fluoro-4-hydroxybenzeneacetic acid 458-09-3 A21994 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.

(3-Fluoro-4-hydroxy-phenyl)-acetic acid 3-Fluoro-4-hydroxybenzeneacetic acid 458-09-3 A21994 (CAS 458-09-3) is a high-purity analytical reference standard with the molecular formula C8H13FO3 and a molecular weight of 176.19 g/mol.

The molecular framework of (3-Fluoro-4-hydroxy-phenyl)-acetic acid 3-Fluoro-4-hydroxybenzeneacetic acid 458-09-3 A21994 (C8H13FO3) is characterized by a carboxylic acid group, 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
