Description générale

Zinc perchlorate hexahydrate is a hexahydrate salt of zinc widely used as an oxidation reagent and catalyst in various organic transformations. It also finds application in the field of rechargeable batteries.[1][2]

Application

Zinc perchlorate hexahydrate can be used as a catalyst:
  • For acylation of electron-deficient phenols, sterically hindered alcohols and amines.[1]
  • For the synthesis of 2-hydroxy sulfides by the opening of epoxide rings with thiols.[3]
  • For solvent‐free condensation of carboxylic acids with alcohols.[4]
It can also be used as:
  • An electrolyte for aqueous Zinc batteries.[2]
  • A precursor for the synthesis of highly fluorescent ZnSe quantumdots.[5]

Methods of Synthesizing Monodisperse Colloidal Quantum Dots

Colloidal quantum dots (CQDs) are semiconducting crystals of only a few nanometers (ca. 2–12 nm) coated with ligand/surfactant molecules to help prevent agglomeration.

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.
