    Storage

    Store lyophilized at -20ºC, keep desiccated.
    In lyophilized form, the chemical is stable for 36 months.
    In solution, store at -20ºC and use within 3 months to prevent loss of potency. Aliquot to avoid multiple freeze/thaw cycles.

    Solubility
    In vitro DMSO Insoluble
    Water 88 mg/mL
    Ethanol Insoluble
    * <1 mg/ml means slightly soluble or insoluble.
    * Please note that Adooq tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.
