Chemical Structure
Description
The occurrence of 3,3'-Dimethyl-[1,1'-biphenyl]-4,4'-diol 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.
3,3'-Dimethyl-[1,1'-biphenyl]-4,4'-diol (CAS 612-84-0), molecular formula C14H14O2 and molecular weight 214.26 g/mol, is a CATO reference standard with documented purity and traceability.
3,3'-Dimethyl-[1,1'-biphenyl]-4,4'-diol (C14H14O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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), 3,3'-Dimethyl-[1,1'-biphenyl]-4,4'-diol 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.
