Chiral technologies and services

CPS has assembled an industry-leading portfolio of technologies with specific strengths in chiral chemistry. Our main focus is on catalysis as this provides long-term advantages and sustainability for chemical processing. Technologies include: asymmetric hydrogenation, hydro-formylation and biocatalysis – working together with customers we have proven ability to select and combine technologies to deliver optimal solutions to even the most challenging of projects.

Activated mPEGs

Over the last five years, CPS has manufactured and supplied activated mPEGs for the conjugation of proteins, antibody fragments and peptides; to improve the stability and the pharmaco-kinetic properties of biologic drugs. With outstanding GMP capabilities and back integration to high purity mPEG-OH, we can guarantee the quality and security of supply of our activated mPEG products.
