PEG Raw Material

Biopharma PEG supplies linear methoxy & multi-arm PEG raw materials ( PEG hydroxyl or PEG alcohol) with high purity and low polydispersity in large batch sizes. These PEG raw materials are suitable for activation into PEG derivatives. 

Biopharma PEG has rich experience and advanced technology in the polymerization of PEG, and can precisely control the key indicators such as feeding rate, reaction pressure, flow velocity, flow rate and weight during the high-temperature and high-pressure polymerization reaction, so as to reduce impurities and by-products and guarantee high purity and low polydispersity of PEG raw materials.

Meanwhile, we are equipped with a series of advanced analytical equipment such as NMR, MS, HPLC, etc. We have established a mature QA & QC system from raw materials to different derivatives in the process of practice.

Several PEG raw materials with a large stock are listed below, Contact us at for more details.
