Product Description:

mPEG-O-C12는 에테르 결합을 통해 하나의 C12 알킬을 가진 linear methoxy PEG입니다. polyethylene glycol dodecyl ether 는 amphiphilic, surfactant-like polymer입니다. PEG surfactant는 미셀 형성, 약물 용해성 향상 및 제형과 생체이용률 개선을 위한 약물 전달 시스템 구축에 유용합니다. 아미드 결합 또는 가수분해성 에스터 결합을 통해 C12에 부착된 mPEG도 공급 가능합니다.

Properties:

• Molecular weight: MW of PEG was measured by MALDI-MS or GPC. PDI (polydispersity index) of our linear PEG is 1.02-1.05 with very narrow MW distribution. The number of repeating ethylene oxide units (CH2CH2O) or the degree of polymerization is calculated dividing the PEG MW by 44 (44 is the molecular mass of one repeating unit).
• Solubility: Soluble in water and aqueous buffer, chloroform, methylene chloride, DMF, DMSO, and less soluble in alcohol, toluene. Not soluble in ether.
• Density: PEG density is approximately 1.125 g/mL
• Physical form: PEG products generally appear as white or off-white powder, and for very low MW linear PEG such as MW 1k or less, it may appear as wax-like, semi-solid material due to the low MW and the type of functional groups.
• Storage condition: PEG product shall be stored in the original form as received in a freezer at -20C or lower for long term storage. Stock solution of PEG reagents that do not contain oxygen or moisture sensitive functional groups may be temporarily stored in a refrigerator or ambient temperature for multiple days. Stock solution should avoid repeated freeze-and-thaw cycles. See Documents section for detailed storage and handling conditions.
