Product name: Hydrxypropyl- gamma-cyclodextrin
Synonyms: hydrxypropyl- gamma-cyclodextrin / hydrxypropyl-γ-cyclodextrin
CAS#: 128446-34-4
Abbreviation: HPGCD
Qaulity:Pharma grade
Standard: Enterprise standard
Characteristics and applications:
Hydroxypropyl gamma cyclodextrin's water solubility increase to 80g/100ml (25 C) furtherly , and hydropropyl gamma cyclodextrin is no longer a single pure product but the coexistence of multiple substituted compounds, with guest molecules when wrapping is not easy to generate inclusion crystallization. Overall, hydroxypropyl - gamma cyclodextrin has a higher solubility in water and stronger anti crystallization ability.
