Obtaining PEG with more than eight units is relatively difficult. As the chain length increases, it is difficult to obtain high-purity long-chain PEG products, accompanied by very low product yields. Meanwhile, obtaining long-chain PEG through chain addition makes it difficult to maintain consistent product quality for each batch due to the multiple synthesis steps and purification challenges.  

    Through our innovative technology, we have the ability to manufacture long-chain monodisperse PEGs in high purities.Therefore, our high-purity PEG lipdis can  reduce the clinical risks associated with the impurity issues of polydisperse PEG lipids. The following are PEG lipids we can offer.

     Alphabiopharm can offer monodisperse long-chain PEG with high purities and low unspecified impurities or homologous through its innovative synthetic and separation technology.
