Molecular Structure
Product Overview	Bisphenol S is an aromatic diol containing two phenolic hydroxyl groups and a sulfone group. It is used as a raw material for polyethersulfone (PESU), functional resins and related derivatives. Royalchem supplies BPS for customers sourcing resin and specialty polymer raw materials.
Quality Specifications	Appearance: White or off-white crystalline powder 4,4′-Bisphenol S assay: ≥99.5% 2,4′-Bisphenol S content: ≤0.5% Water: ≤0.5% Color (Hazen): ≤50 Melting range: 243–250 °C These values are taken from the specification column of the supplied inspection report. Supply must be checked against the agreed specification and the corresponding batch Certificate of Analysis (COA).
Applications	Polyethersulfone (PESU): An aromatic diol raw material for the synthesis of the corresponding specialty polymer. Functional resins and polymer modification: For related materials development, with suitability assessed against formulation, impurity limits and processing conditions. BPS derivatives: An intermediate for the development of related fine chemicals and functional materials.
