With over 15 years of experience at producing functionalized MPEG reagents, BioVectra has the depth of experience and knowledge to prepare high purity products that meet commercial quality standards.  Central to our offerings are access to two suppliers of custom molecular weight, low polydispersity MPEG raw materials. Our proprietary MPEG purification technology, which removes unwanted PEG-diol impurities, also illustrates our ability to deliver innovative solutions to market driven quality requirements.

Using a high quality (low diol, low PDI) MPEG raw material enables BioVectra to produce functionalized derivatives including; propionaldehydes, maleimides, active esters, nitrophenyl carbonates and custom MPEG products, with exceptional purity at competitive prices. Today, BioVectra supplies MPEGs at commercial scale for marketed bio-conjugated drugs and for a number of products in clinical development.

Maleimide PEG is a sulfhydryl (thiol/SH) group reactive PEG derivative that can be used to selectively modify protein, peptide or any other surfaces with available sulfhydryl groups.
