General description

4-Methoxybenzoyl chloride is one of the reactive acylating agents that can react with carboxylic acids, alcohols and amines to yield respective carboxylic anhydrides, esters and amides.

4-methoxybenzoyl chloride reacts with potassium thiocyanate to yield isothiocyanate derivative via nucleophilic addition-elimination mechanism.

Application

  • 4-Methoxybenzoyl chloride can be used as radical precursor in visible-light photocatalysis to synthesize various heterocyclic compounds.[1]
  • It can be used to synthesize acylphosphine ligands for the rhodium-catalyzed hydrosilylation of alkenes.[2]
  • Incorporation of 4-methoxybenzoyl chloride modified indium tin oxide (ITO) as cathode for the fabrication of organic light-emitting diodes (OLEDs) has been reported.[3]
  • 1,3 diketones synthesized from 4-methoxybenzoyl chloride can be used in one pot synthesis of various pyrazole derivatives.[4]
  • It can also be used in the total synthesis of bioactive compounds like echinoside A and salinosporamide A.[5][6]

Questions

1–2 of 2 Questions  

  1. 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

  2. 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
