Your Custom Chemical Synthesis Partner
What is the Commercial Custom Synthesis Process?
Apollo Scientific’s custom synthesis service is based on collaboration. We work closely with you to understand your requirements, define project goals, and develop an effective synthesis route. We work alongside you to understand not just the compounds you need, but the science they will enable.
At the start of the custom synthesis process, our experts will work to understand your special requirements, goals, and assess challenges. We then use this information to plan a bespoke synthesis process, and provide you with a quote. This collaborative development ensures that our synthesis aligns perfectly with your research goals, providing you with the best possible foundation for discovery.
Whether you’re in the initial stages of your research, in the process of a clinical trial, or scaling up towards commercialisation, our team is here to support you. We ensure that each compound advances your project by bringing our synthetic capabilities to your table, offering both innovation and practical application.
What techniques are used in Custom Chemical Synthesis?
We specialise in manufacturing small multifunctional and unusual substituted arenes and heterocycles. Currently we carry out reactions between -78°C and +250°C in conventional 50mL to 20L glass vessels under inert reaction conditions if required. As well as conventional batch synthesis, we operate a flow reactor system to assist with new reaction development and simple scale up of optimised reactions.
The analytical rigour we apply ensures that each molecule we deliver meets stringent quality criteria, tailored to your specifications. Our laboratories are equipped with the latest analytical instruments, allowing us to verify the purity and stability of the compounds we produce.

Some of the techniques we use to synthesise custom chemical compounds include:
- Asymmetric synthesis using chiral auxiliary, catalysis, and resolution techniques
- Metal-mediated reactions
- Hydrogenation
- Fluorination, phosphorylation and sulfation chemistry
With Apollo Scientific as a partner and chemical supplier, you’re always one step ahead.
