Creatine monohydrate 99.9% White crystal or powder Yuanjinchem

Creatine Monohydrate is the monohydrate form of creatine similar or identical to endogenous creatine produced in the liver, kidneys, and pancreas. Pure creatine is a white, tasteless,odorless powder, that is a naturally occurring metabolite found in muscle tissue.Creatine monohydrate is an amino acid produced in the human body that plays a role in replenishing the energy supply to muscle cells.Creatine is usually produced to a purity of 99.5 percent or higher.Until recently, the primary use for creatine was as a laboratory reagent, demand for which was relatively limited.In the early 1990's, however, weight trainersand other athletes began using creatine in the belief that it stimulates muscle growth and reduces muscle fatigue.
Creatine monohydrate is a colorless, crystalline substance used in muscle tissue for the production of phosphocreatine, an important factor in the formation of adenosine triphosphate (ATP), the source of energy for muscle contraction and many other functions in the body.
Likely impurities are creatinine and other guanidino compounds. It crystallises from the minimum volume of boiling H2O as the monohydrate. The hydrate is also obtained by dissolving in H2O and adding Me2CO. Drying under vacuum over P2O5 or drying at 100o gives the anhydrous base. The anhydrous base can be obtained also by dissolving the hydrate in H2O, seeding with the anhydrous base and cooling in ice. A m of 258 -268o(dec) was reported. The picrate crystallises from 17 parts of H2O with m of 218-220o(dec). [King J Chem Soc 2377 1930, Hoffmann et al.
