Product Description
Bis[4-(2-hydroxyethoxy)phenyl] sulfone, also identified as 2,2'-[sulfonylbis(4,1-phenyleneoxy)]diethanol, is an aromatic sulfone compound with the molecular formula C16H18O6S and a molecular weight of 338.37. The molecule consists of two para substituted phenyl rings linked through a sulfone group, with each ring carrying a 2-hydroxyethoxy side chain that terminates in a primary hydroxyl group. This arrangement combines the thermal and chemical stability of the diphenyl sulfone core with the reactivity of two aliphatic hydroxyl functions.
The product is supplied as a white to almost white powder or crystalline solid with a melting point of 179-183 C. It dissolves to an almost transparent solution in hot methanol, and its low vapor pressure at ambient temperature makes it convenient for weighing and formulation work. Predicted physical constants include a density of approximately 1.33 g/cm3, a boiling point of 582.5 C at 760 mmHg and a refractive index of 1.587.
Because it carries two hydroxyl groups on an aromatic sulfone skeleton, this compound is valued in polymer laboratories as a monomer, co monomer and chain terminator. In polyether sulfone synthesis it can be used to introduce hydroxyphenyl type end groups or flexible ether segments into the backbone, which is relevant to membrane resin and specialty engineering plastic research. It also serves as a reference material in analytical and synthetic studies of sulfone containing compounds.
Dideu Group supplies this item from gram scale for laboratory evaluation up to kilogram quantities for pilot production. The minimum order quantity is 1 g, and standard lead time is within 7 working days. Shipment is arranged by courier or by air for small packs, and by air or by sea for larger orders. Batch documentation including COA and technical data sheet is issued with each delivery.
Applications
High Performance Polymer Research
Used as a diphenyl sulfone monomer in the study of sulfone based high performance polymers, where the two hydroxyethoxy groups provide defined reactive sites for condensation polymerization.
Polysulfone and Polyether Sulfone Modification
Applied as a hydroxyl containing building block in polyether sulfone systems, where it may be used to introduce hydroxyphenyl end groups or to adjust molecular weight and end group functionality of the resin.
Membrane Material Development
Relevant to research on sulfone based ultrafiltration and separation membranes, where hydroxyl functional sulfone monomers may be used to improve hydrophilicity and surface properties of the membrane polymer.
Polyester and Polyurethane Synthesis
As an aromatic diol, it may be used as a chain extender or co monomer in polyester and polyurethane systems where additional rigidity and thermal stability are required in the polymer backbone.
Organic Synthesis and Analytical Reference
Serves as an intermediate for further derivatization of the hydroxyl groups, and as a reference compound in structural and analytical studies of diphenyl sulfone derivatives.
Note: the entries under Membrane Material Development and Polyester and Polyurethane Synthesis are based on the functional structure of this compound and on typical uses of related aromatic diols. They are presented as potential directions rather than confirmed industrial applications.
