Product Description

Product Description
Hydroxypropyl-Gamma-Cyclodextrin CAS#128446-34-4
Cas No.: 128446-34-4
Molecular Formula:C63H110O45
Molecular Weight: 1587.5394
EINECS No.:207-166-5
Alias:HYDROXYPROPYL-GAMMA-CYCLODEXTRIN (HGC) 4 5% W/V SOLUTION IN H2O; HYDROXYPROPYL-GAMMA-CYCLODEXTRIN, MS=0.6; .gamma.-Cyclodextrin, 2-hydroxypropyl ethers; CAVASOL(R)W8; Hydroxypropyl-gamma-cyclodextrin
Melting point: 52-55℃(lit.)
Boiling point:97-98℃3 mm Hg(lit.)
Flash Point:>230℉
Solubility in water:Soluble in water
Hydroxypropyl gamma cyclodextrin has a slightly larger cavity than gamma cyclodextrin, can accommodate a larger substrate than betacyclodextrin, has a higher water solubility, and is more resistant to crystallization
Application:
the hydroxypropyl-γ-cyclodextrin has a higher solubility in water, a stronger resistance to crystallization precipitation ability. Overall, hydroxypropyl-γ-cyclodextrin has higher solubility in water and stronger resistance to crystallization. γ-cyclodextrin solubility in water is 23.2g/100ml (25℃), but the solubility still limits its application in some cases.
It is recommended to be used in higher value-added products, such as pharmaceuticals, health care products, cosmetics and other specialty materials or hydroxypropyl-β-cyclodextrin incapable of encapsulation of larger molecules to deal with.
Pakcage:1kg/bag or 20kg/drum
Storage: Keep in a tightly closed container and store in a cool, dry, dark, ventilated area. When the temperature is higher than normal temperature, the
product is easy to melt and cause caking. If caking occurs, it can be crushed under dark conditions and then continue to use. Effective from the date of production
Standard :USP, EP,CP, In-house Standard
