The Diosgenin is flaky or needle crystal which is soluble in gasoline, ethanol, chloroform and other organic solvents, insoluble in water. The product's categories are pharmaceutical intermediates, fine chemical & intermediates, APIs, biochemistry, steroids and the group of Dioscin.

The sugar-free (aglycone), Diosgenin is used for the commercial synthesis of cortisone, pregnenolone and other steroid products. It is also the precursor for the semisynthesis of progesterone which in turn was used in early combined oral contraceptive pills.

The Diosgenin is irritating to eyes, respiratory system and skin. In case of contact with eyes, rinse immediately with plenty of water and seek medical advice. If swallowed, wash out mouth with water provided person is conscious. If inhaled, remove to fresh air. If breathing becomes difficult, call a physician. In case of skin contact, flush with copious amounts of water for at least 15 minutes. Remove contaminated clothing and shoes. If you want to contact this product, you must wear suitable protective clothing and gloves.
