Chemical and Physical Properties of Tamoxifen Citrate

　　Tamoxifen Citrate is a white or pale yellow crystalline powder which is sparingly soluble in ethanol (95%), slightly soluble in water, practically insoluble in ether. A calibrated dropper is provided with each bottle to assure accurate measurement.


　　Each bottle contains 30ml solution at 20 milligrams (mg) per milliliter (ml) - in etOH/ Glycerin (Ethyl Alcohol and Glycerin). The total amount of Tamoxifen Citrate per 30ml bottle is 600mg which is in solution and does not need to be shaken or stirred prior to administration.

　　Storage Information: Room temperature.

　　The solution may be stored at room temperature and remains stable at the above listed concentration effective until the expiration date listed on the bottle. The product will still remain active after the date of expiration but the concentrations and/or activity of the Tamoxifen Citrate cannot be guaranteed to remain intact after the listed expiration date.
