    View the MSDS for this product
    Isoflavone derivative found in soy-based food products.  Wang, H. and Murphy, P.A.  "Isoflavone content in commercial soybean foods."  J. Agric. Food Chem. 42:  1666-1673 (1994). We have been informed that aqueous or alcoholic solutions can undergo substantial decomposition less than a day after being prepared, particularly if they are held at room temperature.
    STABILITY: 
    Very little information about the stability of this compound is available at present.  The 1 mg size (+ ca. 2-3%) consists of a film adhering to the walls of the ampule and may not be easily subdivided by weighing. The larger sizes contain a weighable powder.
    We recommend that this product be stored in bulk in the dry state, with a desiccant, at the coldest available temperature.  Small working quantities of solutions should be made up just prior to use. In our experience, when stored in the dry state, frozen and desiccated, this compound has retained its original purity for several years.
