The molecular framework of 6,6'-((2-Hydroxy-5-methyl-1,3-phenylene)bis(methylene))bis(2,4-dimethylphenol) (C25H28O3) is characterized by a steroid core, 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
6,6'-((2-Hydroxy-5-methyl-1,3-phenylene)bis(methylene))bis(2,4-dimethylphenol) (CAS 35924-04-0) is a high-purity analytical reference standard with the molecular formula C25H28O3 and a molecular weight of 376.49 g/mol.
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.
CATO manufactures 6,6'-((2-Hydroxy-5-methyl-1,3-phenylene)bis(methylene))bis(2,4-dimethylphenol) under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
