Product overview

Methotrexate disodium salt is the disodium salt form of methotrexate, an antimetabolite and antifolate agent that inhibits dihydrofolate reductase, thereby preventing the conversion of folic acid into tetrahydrofolate and inhibiting DNA synthesis. It is a light yellow to yellow crystalline powder with improved water solubility, widely used as an antineoplastic API and pharmaceutical intermediate. in water. In acidic solutions, it is colorless, while in basic solutions, it turns pink to purple.
