Huateng Pharma Supplies Monodisperse PEGs And Polydisperse PEGs in Large Quantities

July 26, 2022

Polyethylene glycol (PEG) is a polyether compound derived from petroleum. It is a biocompatible, synthetic, hydrophilic polyether compound that has many widespread use in the biomedical industry including bioconjugation, drug delivery, surface functionalization, and tissue engineering. It also used in chemical and industrial sectors. PEGs can be classified as Monodisperse PEG and Polydisperse PEGs.

What's the difference between monodisperse and polydisperse PEGs?

Most of the polyethylene glycol (PEG) compounds currently available on the market are polymers formed by polymerization of ethylene glycol. The molecular weight of polydisperse PEG is uncertain and distributed in a certain range. The polydispersion index (PDI) is commonly used to determine how narrow the molecular weight distribution is. Monodispersed PEG are pure compounds with precise PEG units and a single molecular weight. In contrast, polydispersed PEG is a polymer mixture with an average molecular weight, such as 5K, 10K, etc.

Huateng Pharmaceuticals is a professional supplier of PEG derivatives with thousands of PEG derivatives, covering monodisperse PEGs, polydisperse PEGs and PEG raw material with molecular weights ranging from 200 to 4w.

We have our own raw material manufacturing base and production management team who have decades of experience in factory production and management, to ensure the lowest cost, the fastest speed and the highest quality according to various customer requirements” said the Production Director of Huateng Pharma, We are able to supply high quality and large quantities of monodisperse and polydisperse PEGs from grams to kilograms.

Polyethylene glycol and its derivatives are one of the few polymers approved by the FDA for use in biomedical products. Functional polyethylene glycol is widely used in drug pegylation, biomedical technology, nanotechnology, polymer engineering and other fields, and its application in drug PEGylation is particularly important.

Monodisperse polyethylene glycol derivatives generally refer to polyethylene glycol derivatives with a relatively small molecular weight and a single molecular weight. The number of PEGs varies from 2 to 36. Monodisperse polyethylene glycol derivatives have the advantages of molecular weight determination, easy purification and characterization, and high batch reproducibility, which can be used in drug delivery, drug carrier, protein modification and many other aspects. Polydisperse PEGs are very useful in the development of PEGylated protein drugs. The polydisperse PEGs increases the bulk around the drug and lowers clearance rate. This also reduces the dose required. Polydisperse PEGs are ubiquitously used in pharmaceutical industry and biomedical research.
