The following new drugs have been approved for human use: ethynylestradiol and norethindrone acetate; aspirin, phenacetin, caffeine and orphenadrine citrate; norethindrone and mestranol; lidocaine, Bi subgallate, ZnO, Al subacetate, and Peruvian balsam; nalidixic acid; lidocaine; pralidoxime chloride; ammonium form of cross-linked polyacrylic (carboxylic) cation-exchange resin; and for veterinary use: trichlorfon, phenothiazine, and piperazine-di-HCl. In the experiment, the researchers used many compounds, for example, Piperazine Dihydrochloride (cas: 142-64-3Recommanded Product: 142-64-3).
Piperazine Dihydrochloride (cas: 142-64-3) belongs to piperazine derivatives. Piperazine is a fairly basic compound and is an amine solvent. Two common salts in the form of which piperazine is usually prepared for pharmaceutical or veterinary purposes are the citrate, 3C4H10N2.2C6H8O7 (i.e. containing 3 molecules of piperazine to 2 molecules of citric acid), and the adipate, C4H10N2.C6H10O4 (containing 1 molecule each of piperazine and adipic acid).Recommanded Product: 142-64-3
