Description

Impurity Methotrexate EP Impurity B
Applications Aminopterin (Methotrexate EP Impurity B) is a folic acid antagonist. Its actively transported into cells by thefolate transporter. In the cell, its converted to a high molecular weight polyglutamate metabolite by folylpolyglutamate synthase, that, in turn, binds to dihydrofolate reductase and inhibits its activity.
Not a dangerous good if item is equal to or less than 1g/ml and there is less than 100g/ml in the package
