Chemical Structure
Description
2,2-Diphenylpropionic acid 2,2-diphenyl propionic acid alpha,alpha-diphenylpropionic acid 5558-66-7 (CAS 5558-66-7) is a high-purity analytical reference standard with the molecular formula C15H26O2 and a molecular weight of 238.37 g/mol.
The molecular framework of 2,2-Diphenylpropionic acid 2,2-diphenyl propionic acid alpha,alpha-diphenylpropionic acid 5558-66-7 (C15H26O2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage. 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 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), 2,2-Diphenylpropionic acid 2,2-diphenyl propionic acid alpha,alpha-diphenylpropionic acid 5558-66-7 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.
