General description

Trans-stilbene oxide also known as trans-1,2-Diphenyloxirane, is often used in photochemistry, whereit can change its structure when exposed to light.Stilbene oxides can break apart when they are excited bylight, leading to the formation of carbonyl ylides. It is also commonlyused to produce trans-stilbene sulfides. [1]

Application

  • Chiral Stationary Phases for Liquid Chromatography: Trans-stilbene oxide has been utilized in the fabrication of cellulose derivative-coated spherical covalent organic frameworks, serving as chiral stationary phases for high-performance liquid chromatographic enantioseparation, demonstrating its pivotal role in advanced analytical methodologies (Yan et al., 2022).
  • Method Selection for Chiral High-Performance Liquid Chromatography: Its application extends to the utilization of hysteresis phenomena for chiral high-performance liquid chromatographic method selection in polar organic mode, enhancing the efficiency and specificity of pharmaceutical compound analysis (Horváth et al., 2020).
  • Adsorption Properties for Enantioseparations: The effect of chiral selector loading on the adsorption properties of fully- and superficially-porous particles is crucial for high-efficient ultrafast enantioseparations, where trans-stilbene oxide derivatives play a significant role (Felletti et al., 2018).
  • Catalysis in Alkene Epoxidation: Trans-stilbene oxide is involved in innovative catalysis research, specifically in the development of carbon nitride-supported Fe(2) cluster catalysts for alkene epoxidation, showcasing its utility in sustainable chemical synthesis (Tian et al., 2018).

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
