General description

We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. This product has been enhanced for energy efficiency. Find details here.

Application

Direct intercalation into C60 results in the superconducting material (NaH)4C60.
Sodium hydride (dry) (NaH) can be used for a variety of applications such as:
  • preparation of sodium aluminum hydride (NaAlH4), which can be used as a hydrogen storage material
  • a base and a reducing agent for the deprotonation of alcohols, phenols, amides, ketones, and different functional groups
  • a hydride donor that can be used in various reactions such as nitriles, amides, and imines
  • for potential usage in thermal energy storage

  1. Which document(s) contains shelf-life or expiration date information for a given product?

    If available for a given product, the recommended re-test date or the expiration date can be found on the Certificate of Analysis.

  2. How do I get lot-specific information or a Certificate of Analysis?

    The lot specific COA document can be found by entering the lot number above under the "Documents" section.

  3. What impurities are present in the Product 223441, Sodium Hydride?

    We have not performed impurity profiling on this product and therefore can not provide an impurity profile.  Impurities may include unreacted starting materials, residual solvents, reaction byproducts, etc.

  4. The website states Product 223441, Sodium Hydride, is packaged in a metal can, can you give me more details on the container type?

    The Sodium Hydride will have been packaged under a Nitrogen atmosphere.  The material will be a plastic bag and  sealed inside of a metal can (paint can where you can pop the lid off).  On the top of the can, there will be a plastic ring sealing the lid.  This ring will need to be removed in order to open the can.

  5. Besides water, are there other materials that Product 223441, Sodium Hydride. will react hazardously with?

    Yes, per the Hazardous Laboratory Chemicals Disposal Guide, 2nd Edition, the following should also be avoided:Acetylene reacts vigorously in the presence of moisture even at -60oC. Air - the finely divided dry powder ignites in dry air. Halogens incandesces in Chlorine or Fluorine at room temperature and in Iodine at 100o C. Sulfur Dioxide -  reacts explosively with Sulfur Dioxide. Addition to water even in small amounts will result in explosion.

  6. What is Product 223441, Sodium Hydride, soluble in?

    Per the Merck Index, 13th Edition, it reacts explosively with water, violently with lower alcohols, ignites spontaneously on standing in moist air.  Soluble in molten Sodium Hydroxide, insoluble in liquid Ammonia.

  7. If Product 223441, Sodium Hydride, should start on fire, what is the best way to extinguish the fire?

    Use only a Metal-X (Class D) type extinguisher to extinguish the fire.Do not use water, carbon dioxide, or halocarbon extinguishers. 

  8. How do I find price and availability?

    There are several ways to find pricing and availability for our products. Once you log onto our website, you will find the price and availability displayed on the product detail page.
