General description

4-tert-Butylphenol is a phenol derivative. Its contact with skin may lead to leukoderma. It is widely used in the polymer industry.[1] Reaction of 4-tert-Butylphenol with mushroom tyrosinase has been reported to afford 4-t-butyl-o-benzoquinone and kinetics of this enzymatic reaction has been investigated.[2]

Application

4-tert-Butylphenol is suitable reagent used in kinetic study of hydroxylation of 4-tert-butylphenol by mushroom tyrosinase.[2] It may be used in the synthesis of calix[7]arene.[3]
4-tert-Butylphenol may be employed as carbon and energy supplement in the culture medium of Sphingobium fuliginis strains.[4]

The reaction between 4-tert-butylphenol (BuPhOH) and mushroom tyrosinase was investigated by following 4-tert-butyl-ortho-benzoquinone, whose high stability permits the reaction to be used as a model for the study of the monophenolase activity of tyrosinase. The system evolves to a pseudo-steady

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.
      For more information, please refer to the Product Dating Information document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/418/501/product-dating-information-06-25-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
