Challenging Chemistry?
An overseas CRO had been working for 8 months to enable scaling up from 10mg synthesis to 1g synthesis but a troublesome step did not allow scale up further than 100mg. NuChem was mandated to investigate the issue and within 2 days, NuChem identified the problem as an undesired reaction pathway leading to a side product. We redesigned the route which enabled a 1 kg synthesis to proceed a few months later.
Synthetic Chemistry Mandates
Custom synthesis
At NuChem Sciences our team of chemists possesses extensive experience in synthetic chemistry. We provide custom synthesis services to both academia and industry. Whether your target is a single compound, a set of compounds or a compound library, we are dedicated to executing each project to the high standards expected by our clients. Our knowledgeable and resourceful scientists are capable of tackling and solving the most challenging synthetic problems.
- FFS or FTE
- Assess project status and identify chemistry issues
- Resolve chemistry issues
- Enable core synthesis
- Enable analog synthesis
- Project management
Medicinal Chemistry Mandates
Medicinal Chemistry is a core expertise of NuChem Sciences. Our primary asset is our knowledgeable, experienced, and creative scientists who draw upon years of experience in early stage drug discovery acquired across a wide range of therapeutic areas and biological targets. Through hit identification and productive analogue design and synthesis, we can help you identify and optimize pre-clinical candidates in the area of small molecule drug discovery. NuChem delivers excellence through thoughtful interpretation and rational integration of tractable SAR and PK/ADME results into the design-make-test-analyze cycle. Our medicinal chemistry team is committed to rapidly advancing your research programs by providing fast, flexible and innovative solutions.
- Same as synthetic chemistry plus
- Design and synthesis of analogs or focused libraries
- Work with biology to generate, compile and analyze data
- Work with computational to establish SAR
- Project management including external service providers

Route Scouting and Process Development
Our process development group is composed of highly skilled and creative organic chemists having significant experience in synthetic process development of drug candidates, intermediate compounds, and building blocks. The group uses state of the art chemistry methodologies and creative design of synthetic routes to develop processes suitable for the large-scale manufacturing of drug candidates, and executes the preparation of complex challenging molecules in house using these processes. We work as an extension of our customer’s internal R&D teams providing high quality FTE services at competitive rates and meeting project timelines.
