Application | 5-methylpyrazine-2-formic acid, also known as 2-methyl-5-formic acid, is an important pharmaceutical intermediate It is mainly used to prepare an important hypoglycemic drug glipizide and a new generation of long-acting lipid-lowering drug acipimox. At the same time, its derivative 2-methyl-5-pyrazinemethyl formate is also an important drug for the treatment of tuberculosis. |
uses | intermediates of the hypolipidemic drug Amoxidus. It is the intermediate of the drug glipizide and lezhiping, the lipid-lowering drug amoxex. |
Production method | It can be prepared by electrolytic oxidation of 2, 5-dimethyl or 2-methyl-5-(substituted) methylpyrazine. |
