General description

Lithium hydroxide monohydrate is a lithium salt. Crystal structure study reveals it has monoclinic structure with space group C2/m.[1] Its vibrational spectra has been studied using IR, Raman and inelastic neutron scattering (INS) spectroscopy.[2] It is reported to transform the surface of titania monoliths to form flower like structures.[3]

Application

Lithium hydroxide monohydrate may be used to produce naphtoxy ion during the synthesis of allyl 1-naphthyl ethers.[4]
It may be used in the synthesis of the following:
  • Lithium titanate (Li4Ti5O12) heterogeneous nanostructures.[5]
  • Tin oxide-carbon (SnO2/C) nanocomposites.[6]
  • Zinc oxide (ZnO) nanowire arrays.[7]
  • Lithium diborate gel films.[8]
  • Porous layered lithium cobalt oxide (LiCoO2) films.[9]

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
