產品名稱：6"-O-Malonylgenistin, Free Acid
產品貨號：LC  M-8090
產品規格：10 MG
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).
Typical purity at time of shipment is >99%; this figure may include small amounts of monomalonyl hemiesters other than the 6"-isomer.
The 1 mg size (accuracy is ± ca. 2-3%) consists of a film adhering to the walls of the ampule and cannot be easily subdivided by weighing.  The larger sizes contain a weighable powder.
STABILITY:  Very little information about the stability of this compound is available at present.  In our experience, when stored in the dry state, frozen and desiccated, this compound has retained its original purity for many months.  Our manufacturing process results in a highly crystalline, stable form of this product, and it does not need to be shipped on ice.  Our thermal tests show that heating our dry product at 85 ºC for 10 hours in air gives only ca. 1% decomposition.  However, we have been informed that aqueous or alcoholic solutions at various pH's can undergo substantial decomposition less than a day after being prepared, particularly when held at room temperature.  We recommend that this product be stored in bulk in the dry state, very, thoroughly desiccated, at the coldest available temperature.  Small working quantities of solutions should be made freshly each day, just prior to use, and should be discarded daily.  Thaw containers to room temperature prior to opening and minimize exposure to air during handling to keep moisture levels low.
Storage:  Store desiccated at or below -20 ºC.  Solubility:  Soluble in DMSO, methanol, ethanol, or mixtures of acetonitrile/water.  Disposal:  A
