General description

4,4′-Sulfonyldiphenol also known as Bisphenol S(BPS) is a monomer characterized by its sulfone group (-SO2-) linking two phenolic rings. Its unique chemical structure imparts high thermal stability, chemical resistance, and tensile strength. It is often used as a monomer or additive in the synthesis of high-performance polymers, particularly polyethersulfones (PES) and polyphenylsulfones (PPSU). It is widely used in the field of polymer synthesis, medical devices, and dental composites.

Application

4,4′-Sulfonyldiphenol can be used:
  • As a monomer to synthesize fibrous poly(arylene ether ketone)s with excellent water affinity, thermal stability and film forming capability. This can be utilized to fabricate Proton exchange membranes for electrodialysis, fuel cells and flow batteries.
  • As a precursor to prepare polyphosphazene-based contrast agents for magnetic resonance imaging (MRI) and computed tomography (CT). It enhances the thermal stability, chemical resistance and allows easy functionalization of contrast agents.
  • As a monomer to prepare poly (cyclotriphosphazene-co-4,4-sulfonyldiphenol) (PZS) coating for separators, in lithium-ion battery. The coated separators show sufficient enhancement of liquid electrolyte wettability and ionic conductivity, resulting in better cycle performance.

Questions

1–2 of 2 Questions  
  1. How can I determine the shelf life / expiration / retest date of this product?

    1 answer
    1. If this product has an expiration or retest date, it will be shown on the Certificate of Analysis (COA, CofA). If there is no retest or expiration date listed on the product's COA, we do not have suitable stability data to determine a shelf life. For these products, the only date on the COA will be the release date; a retest, expiration, or use-by-date will not be displayed.
      For all products, we recommend handling per defined conditions as printed in our product literature and website product descriptions. We recommend that products should be routinely inspected by customers to ensure they perform as expected.
      For products without retest or expiration dates, our standard warranty of 1 year from the date of shipment is applicable.

  2. How is shipping temperature determined? And how is it related to the product storage temperature?

    1 answer
    1. Products may be shipped at a different temperature than the recommended long-term storage temperature. If the product quality is sensitive to short-term exposure to conditions other than the recommended long-term storage, it will be shipped on wet or dry-ice. If the product quality is NOT affected by short-term exposure to conditions other than the recommended long-term storage, it will be shipped at ambient temperature. As shipping routes are configured for minimum transit times, shipping at ambient temperature helps control shipping costs for our customers. For more information, please refer to the Storage and Transport Conditions document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/316/622/storage-transport-conditions-mk.pdf
