General description

Biphenyl-4,4′-dicarboxylic acid (BPDC) belongs to the class of monomers known as aromatic dicarboxylic acids. It is used to prepare BPDC-based polymers, which exhibit excellent thermal stability, making them suitable for applications where high-temperature resistance is required. These polymers also demonstrate high electrical insulation properties due to their low dielectric constant and high breakdown strength. They find applications in the electrical and electronics industry for insulation, encapsulation, and fabrication of high-performance electronic devices.[1]

Application

Biphenyl-4,4′-dicarboxylic acid can be used:
  • As a key component In the synthesis of nematic aromatic polyesters which are valuable in the development of liquid crystal polymers with potential applications in electronics, optical devices automotive, and textiles.
  • As a linker or ligand in the synthesis of metal-organic frameworks (MOFs) for a wide range of potential applications in areas such as gas storage, catalysis, sensing, and separation technology.
  • As a building block in biomedical applications for the synthesis of various pharmaceutical compounds and materials with biological activity. It can also be utilized in the development of drug delivery systems and biomaterials due to its chemical properties.

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
