The occurrence of alpha,alpha-Dimethoxy-alpha,alpha,alpha,alpha-tetraphenyl-p-xylene is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
alpha,alpha-Dimethoxy-alpha,alpha,alpha,alpha-tetraphenyl-p-xylene (CAS 68883-10-3) is a high-purity analytical reference standard with the molecular formula C34H30O2 and a molecular weight of 470.60 g/mol.
The molecular framework of alpha,alpha-Dimethoxy-alpha,alpha,alpha,alpha-tetraphenyl-p-xylene (C34H30O2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic 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 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), alpha,alpha-Dimethoxy-alpha,alpha,alpha,alpha-tetraphenyl-p-xylene 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.
