Custom Products

Everyone has a catalogue of existing products… We have a catalogue of your future products!

Our focus is on chemical intermediates, in every sector, that are not currently available in the proper quantity or quality. We solve this problem for you.

We can start the project at any stage, in any volume, from preclinical to commercial supply.

Our project managed supply chains provide long-term continuity and stability.

Smart Cost Estimator

Exeris recognizes the importance of cost estimates early on in the development of a new project. Over the course of many projects Exeris has developed a proprietary cost model and its own set of Smart Cost Estimation tools and techniques to make this part of project planning as accurate as possible. We are able to incorporate a comparison of different routes of synthesis.

This is especially important for new chemical entities.  Clients can provide us with the CAS number or structure of the compound and we can provide our best and most reliable estimate, often in less than a week.

Please use the contact form to submit your request for a cost estimate.

Our Strengths in China

We are in position to identify the right manufacturer for each project. On the ground for pre-audits to ensure the quality of the plant, the people and the logistics. Our team in Nanjing develops and maintains strong relationships with our partners. GMP and non-GMP audits can be performed for our projects and also as a service to our customers. Detailed monitoring of project progress through development and into production.

Expertise in the field

Exeris is a recognized partner and leader in the field of Custom Synthesis and complex manufacturing and supply chain. Our perspective on the industry is sought out and appreciated by our partners.
