Where is Glycylglycine used?

• Pharmaceutical formulations: buffering agent maintaining stable pH in injectable solutions, protein therapeutics and lyophilized drug products
• Cosmetics: humectant in moisturizing serums, creams and toners, attracting and retaining moisture at the skin surface
• Biochemical research and peptide synthesis: reference standard and reagent
• In cell culture media and enzyme assay systems it maintains physiological pH without interfering with biological activity.

Commercial specifications

• High-purity lots supporting GMP-compliant manufacturing
• Bulk quantities and smaller research-scale packaging
