索取COA

  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 does Product 230200, Lithium Borohydride, need to be handled under nitrogen?

    This product is moisture sensitive, reacting violently with water, liberating extremely flammable gases.

  4. Is the tetrahydrofuran (THF) used in Product 230200, Lithium Borohydride, stabilized?

    The THF used in this product is stabilized with 0.025% butylated hydroxytoluene (BHT).

  5.  Is it necessary to refrigerate Product 230200, Lithium Borohydride?

    We do recommend to refrigerate this product, since it may develop pressure at room temperature.

  6. What types of reactions is Product 230200, Lithium Borohydride, used in?

    It is reagent for reduction of compounds containing ketonic, aldehydic, or ester carbonyls and a nitrile group, where reduction of the carbonyl but not of the nitrile group is wanted.

  7. Is Product 230200, Lithium Borohydride, an energy carrier?

    Lithium borohydride is renowned for one of the highest energy density chemical energy carriers.  By reacting with atmospheric oxygen, it liberates large amounts of heat.
