Product name: 2-Methyl-1,4-naphthoquinone Alias: Menadione (1.05793); Vitamin K2(0); Vitamin K3; menaphthone; Menadione; Vitamin K_3; 2-Methyl-1,4-dihydronaphthalene-1,4-dione Effective ingredients: Menadione Physical and chemical properties: Molecular formula: C11H8O2, Molecular weight: 172.2. Soluble in hot water and ethanol, soluble in ethanol, insoluble in benzene and ethyl ether, water solution PH4.7-7. Room temperature stability, easy to decompose in light. After pyrolysis of menadione has strong stimulation to the skin, sensitivity to acid, easy to moisture absorption. Characters: white or off-white crystalline powder, lump after moisture absorption. 2, Function Vitamin supplements. Vitamin K for the liver synthetic enzyme factor (B) the necessary material, and participate in the coagulation factor VII, IX, and X synthesis, maintain the animal's blood coagulation processes. A lack of Vitamin K can cause the blood coagulation factor synthesis obstacle, affect the coagulation process and cause bleeding. Vitamin K is also for animals within the body (mainly refers to exist in the liver, bone, testicular, skin and kidney tissues and organs) of Vitamin K dependent function system required carboxylation, bone element (BGP) is an indispensable factor in the process of synthesis. In addition, in the process of high-energy compound metabolism and oxidative phosphorylation, and other aspects of fat-soluble Vitamin metabolism and play an important role, and has diuretic, strengthen the function of the liver detoxification, participate in membrane structure, the function of lowering blood pressure. 3, Adaptives It is mainly used for hemorrhagic illness caused by a lack of Vitamin K. 1. Bleeding: used for obstructive jaundice, bravery Lou, chronic diarrhea, widely bowel resection caused by intestinal absorption dysfunction patients, premature infants, neonatal low prothrombin, coumarin or salicylic acid class and other reasons caused by excessive prothrombin low caused by bleeding. Can also be used to prevent long-term oral broad-spectrum antibiotics drugs caused by Vitamin K deficiency. 2. Analgesia: cholelith disease, biliary tract roundworm disease caused by biliary colic. 3. Save Diphacin poisoning, appropriate large doses at this time.
