Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 330.40 g/mol gives 4,4'-Sulfonylbis[2-(2-propenyl)phenol distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
4,4'-Sulfonylbis[2-(2-propenyl)phenol (CAS 41481-66-7) is a high-purity analytical reference standard with the molecular formula C18H18O4S and a molecular weight of 330.40 g/mol.
The molecular framework of 4,4'-Sulfonylbis[2-(2-propenyl)phenol (C18H18O4S) is characterized by a flavonoid core, a sulfone 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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 4,4'-Sulfonylbis[2-(2-propenyl)phenol 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.
