High Purity Trehalose

Trehalose SG

Trehalose SG by Hiyashibara
Trehalose SG

Trehalose is a dihydrate crystalline  non-reducing disaccharide  consisting of two glucose molecules  linked by an α,α‒1,1 bond. Trehalose SG has been supplied and used for parenteral formulations because of its high purity and low endotoxin specification. Trehalose is unique in its remarkable acid tolerance as well as heat stability and shows no Maillard reaction when heated in solutions containing amino acids. It shows several benefits in stabilizing protein structures when proteins are lyophilized or frozen, and is also known to prevent cells and liposomes from damage during freezing and thawing.



  • Stabilization of antibodies, peptides, and vaccines for injection
  • Stabilization of exosomes
  • Additive for culture medium (e.g., stem cells)
  • Preservation of platelets


  • JP / USP-NF / Ph.Eur. / CP
  • US Type IV DMF, Chinese DMF
  • Kosher, Halal
