Chemical Structure
Description
As a certified reference material (CRM), 2-Phenoxyphenylacetic 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.
2-Phenoxyphenylacetic Acid (CAS 25563-02-4), molecular formula C14H12O3 and molecular weight 228.24 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C14H12O3, 2-Phenoxyphenylacetic Acid contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 228.24 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
