General description

1-Naphthol is a hydroxyl-aromatic compound. Its thermodynamic properties such as heat capacity, sublimation pressure, vapor pressure, enthalpies of combustion, formation and fusion have been estimated.[1] The decomposition of 1-naphthol in aqueous solutions on exposure to gamma radiation has been studied.[2] The ability of biochar of orange peels in adsorbing 1-naphthol from water has been investigated.[3] The activation energy and the reaction rate constant of the enzymatic polymerization of 1-naphthol using laccase have been reported.[4] It undergoes hydrogenation in the presence of a rhodium catalyst to form cis,cis 1-decalol.[5] This product is a certified reference material (CRM) certified to International Standards BS EN ISO / IEC 17025 and ISO 17034 under UKAS accreditation.

Application

1-Naphthol has been used as a prooxidant to analyze its ability to induce hemolysis in a zebrafish G6PD (glucose-6-phosphate dehydrogenase) deficiency model.[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
