  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. Why is Product 212776, Lithium aluminum hydride solution, considered carcinogenic?

    The carcinogen reference comes from Tetrahydrofuran (THF).  The solution is 90% THF.  The THF reference is form the National Toxicology Program (NTP) database.

  4. Product 212776, Lithium aluminum hydride solution, appears to container a precipitate in it.  Is it still OK to use?

    Most if not all solid lithium aluminum hydride will contain some form of insoluble oxides from slight air exposure.  You should be able to filter the insolubles - keeping air exposure to a minimum is the key. This procedure should be done entirely under argon (argon is typically a drier gas than nitrogen). If the final solution is exposed to air at any time, insolubles will be formed which will  then require further filtration to get clear again.
