Frequently Asked Questions
Complex synthetic medicines are advanced therapeutic compounds built through multi-step chemical synthesis. They often feature highly functionalised scaffolds, multiple chiral centres, conjugated domains, or hybrid architectures that combine different modalities such as small molecules, peptides, or oligonucleotides.
Developing these molecules requires deep chemical insight, precision analytics, and scalable process design to ensure purity, stability, and manufacturability. CatSci specialises in creating efficient, sustainable routes that translate these intricate chemistries into development-ready drug substances.
CatSci offers end-to-end services for complex synthetic medicines — from retrosynthetic route design and process optimisation to analytical integration and regulatory support. Our scientists create scalable, convergent, and sustainable pathways for complex scaffolds, conjugates, and high-potency molecules.
CatSci supports a wide range of complex molecules, including multi-domain scaffolds, conjugates, hybrid constructs, and high-potency compounds.
