The IUPAC name of Aminophylline is 1,3-dimethyl-7H-purine-2,6-dione; ethane-1,2-diamine. With the CAS registry number 317-34-0 and EINECS 206-264-5, it is also named as Aminophylline dye free. The product's categories are Miscellaneous Biochemicals; API's. It is white to slightly yellowish powder which is soluble in water, insoluble in ethanol or ether. What's more, it has a slight ammoniacal odor and a bitter taste. Upon exposure to air, it gradually loses ethylenediamine and absorbs carbon dioxide with the liberation of free theophylline. Additionally, it should be stored at the temperature of -20 °C.
