General description

Mesitylene, also known as 1,3,5-trimethylbenzene, is a benzene derivative. Its carbon-13 spin-lattice relaxation times, dipolar relaxation rates and nuclear Overhauser enhancements have been measured to analyze the internal methyl rotation and intermolecular interactions.[1] The anodic oxidation of mesitylene at a platinum electrode in the presence of different electroytes has been investigated.[2] The ring deformation in mesitylene has been studied in the gas-phase by electron diffraction.[3]

Application

Mesitylene may be used to:
  • Grow fullerene(C60)/1,3,5-trimethylbenzene (mesitylene) nanowires.[4]
  • Prepare 2′,4′,6′-trimethyl acetophenone with high slectivity by reacting with acetyl chloride in the presence of dodecatungstophosphoric acid (DTP)/K-10 montomorillonite clay.[5]
  • Synthesize 3,5-dimethylbenzaldehyde from benzene via peroxidative oxidation in the presence of vanadium(IV or V) compounds with N,O-ligands as catalysts.[6]

Questions

1–3 of 3 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.
      For more information, please refer to the Product Dating Information document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/449/386/product-dating-information-mk.pdf

  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
