Guanidinoacetic Acid (GAA)
CAS No: 352-97-6
Molecular Formula: C₃H₇N₃O₂
Molecular Weight: 117.11 g/mol
1. Product Description
Guanidinoacetic Acid (GAA) is the direct precursor of creatine in the body. It appears as a white crystalline powder, is odorless, and is slightly soluble in water. GAA is commonly used as a feed additive to improve energy metabolism, as a raw material for creatine synthesis, and as a nutraceutical ingredient.
