English description(英文原文,共 896 字符)
Product Name:Folinic acid
English Name:Folinic acid
CAS No.:58-05-9
Aliases:Formyl tetrahydrofolic acid, 5-Formyl tetrahydrofolic acid
Molecular Formula:C20H23N7O7
Physical Properties:Pale yellow crystalline powder, odorless, hygroscopic. Freely soluble in water, slightly soluble in ethanol, practically insoluble in chloroform. Unstable under acidic or alkaline conditions, easily decomposed by light. Melting point approximately 250°C (decomposition).
Uses:Folinic acid is an active metabolite of folic acid, used for the treatment of megaloblastic anemia and leukopenia. As an antidote to antifolate drugs, it is combined with methotrexate to reduce its toxicity, and also serves as a folate supplement during chemotherapy.
Technical Specifications:
Assay (on dry basis) ≥98.0%
Loss on drying ≤5.0%
Heavy metals ≤20ppm
Residue on ignition ≤0.1%
Melting point 250°C (decomposition)
