Capabilities

End-to-End Expertise Across
Every Modality

Spanning small molecules to oligonucleotides, peptides, and hybrid modalities, we unite chemistry, bioscience, and analytics to accelerate the development of complex synthetic medicines from discovery to IND and beyond.

Why Modality Expertise Matters

Drug development isn’t a standardised process, and modality-specific challenges rarely fit generic solutions.

Each class of molecule presents distinct synthesis routes, purification hurdles, stability risks, and regulatory expectations. Overlooking these nuances can delay progress, increase costs, and jeopardise quality.

At CatSci, we offer tailored, end-to-end support aligned to your modality, development stage, and commercial objectives. Whether scaling a known class or building a novel platform, we help you move with scientific clarity and operational control.

Excellence in
Cross-Modality Expertise
Oligonucleotides
Our oligonucleotide experts unite chemistry and analytics to accelerate RNA-based therapeutics. From sequence design to conjugation, they deliver decision-ready data and scalable solutions for siRNA, ASO, and emerging nucleic acid platforms.
Peptides
Specialists in complex peptide synthesis, modification, and purification, our team create high-quality linear, cyclic, and stapled peptides. They combine deep chemical insight with analytical rigour to deliver stability, purity, and performance in every sequence.
TACs and Glues
Our targeted protein degradation scientists bring together expertise in bifunctional design, linker chemistry, and biological testing. They turn complexity into robust process understanding - engineering degraders and molecular glues that are stable, scalable, and ready for development.
Hybrid Modalities
At the intersection of chemistry and biology, our hybrid modality scientists develop conjugates and multifunctional platforms that expand the therapeutic potential of these molecules. Our integrated approach ensures structural control, stability, and delivery across modalities.
Small Molecules
Our small molecule scientists design and optimise scalable, efficient routes that balance innovation with manufacturability. Our expertise spans route scouting, process chemistry, solid-state science, and HPAPI development, delivering chemistry that performs from lab to launch.
Complex Synthetic Medicines
Our scientists excel at bridging modalities, integrating small molecule, peptide, and oligonucleotide expertise to develop hybrid constructs and next-generation therapeutics. They thrive on solving the challenges that sit at the edges of chemistry and biology.
Catalysis & Enabling Chemistry
Our catalysis experts push synthetic boundaries using biocatalysis, hydrogenation, and flow chemistry to streamline complex transformations. They design elegant, sustainable solutions that enhance selectivity and scalability.
Translational Bioscience
We design and deliver robust, decision-ready biological assays, from target engagement to phenotypic models, giving you the clarity to move your programme forward with confidence. 
Analytical Services
Our analytical scientists ensure every molecule is understood, controlled, and compliant. From method development to ICH validation, they provide the clarity and confidence that underpin every stage of CMC development.
Route Selection
Our route design specialists define efficient, cost-effective, and sustainable synthetic pathways from the start. They combine retrosynthetic insight with green chemistry principles to de-risk your project and accelerate scale-up.
Purification and Separation Science
Experts in preparative chromatography and chiral separations, our purification scientists deliver the purity, yield, and reproducibility that move programmes forward. They work seamlessly across modalities to isolate excellence in every batch.

How We Work Across Modalities

Integrated From Discovery to Development
Tailored Route Scouting

Early route ideation, chance of technical success planning, costing and retrosynthetic analysis, and sustainability modelling inform smarter decisions before scale-up begins.

Design–Make–Test–Analyse Workflow

Connected chemistry–biology integration accelerates hit-to-lead optimisation and IND readiness with iterative, data-driven insight.

End-to-End Technical Integration

Our teams in chemistry, bioscience, purification, and analytical development collaborate seamlessly, maintaining a single scientific thread across your project.

Custom Purification Workflows

Specialised chromatographic and SFC strategies designed for your molecule’s specific profile and development needs.

Platform Thinking

Holistic, cross-modality strategies that unify discovery and development through shared data, tools, and decision frameworks.

End-in-Mind Approach

Every project is planned with the final goal in sight: from process scalability and stability to regulatory and commercial readiness.

Why Cross-Modality Support Matters

Drug development rarely fits into neat boxes. Molecules evolve, modalities overlap, and innovation happens at the intersections. That’s why cross-functional collaboration isn’t just a benefit, it’s essential.
De-risks development by uniting chemistry, analytics, and biology early
Maintains data integrity and continuity across the entire lifecycle
Enables flexible transition between modalities and scales
Reduces duplication and accelerates decision-making
Builds stronger programmes through collaborative scientific insight
