English description（英文原文，共 935 字符）
Product Name:Calcium levofolinate
English Name:Calcium levofolinate
CAS No.:80433-71-2
Aliases:Levofolinic acid calcium salt, Calcium (6S)-folinate
Molecular Formula:C20H25CaN7O7
Physical Properties:White or off-white crystalline powder, odorless, slightly hygroscopic. Freely soluble in water, slightly soluble in methanol and ethanol, practically insoluble in chloroform and ether. Unstable to light; store protected from light in a tightly closed container.
Uses:As the active form of folic acid, it is mainly used for megaloblastic anemia caused by folate deficiency. In tumor chemotherapy, it serves as a rescue agent for methotrexate detoxification and is combined with 5-fluorouracil for chemotherapy sensitization in malignancies such as colorectal cancer.
Technical Specifications:
Assay (HPLC) ≥98.0%
Specific rotation [α]D20 approximately -15° to -18° (on anhydrous basis)
Loss on drying ≤7.0%
Heavy metals ≤20ppm
