Custom Synthesis
ETA offers expertise in custom synthesis covering all aspects of organic and pharmaceutical chemistry. Our facilities are available for production of intermediates as well as Active Drug Substances under strictly conditions. Whether your need is a multi-step synthesis of 100 mg of a screening candidate or a scale-up to provide several kilograms of an advanced intermediate, you can be assured that your project will receive high priority and personal attention. All our Custom synthesis materials receive full characterization with high field NMR, mass spec, HPLC purity and a full certificate of analysis.

The services offered include:
Process development
Process optimization 
Scale up 
Full custom synthesis
Building blocks & scaffolds
Synthesis of small compound libraries

Contract Manufacturing
If you want to outsource the production of chemicals or ingredients, including Active Pharmaceutical Ingredients (APIs), advanced intermediates. We offer the facilities, knowledge, and experience you need. With a decade’s experience in custom synthesis and process development, we know how to move your product seamlessly from the laboratory into commercialization.
ETA have invested on several multi-purpose manufacturing facilities in different scale, which is available for production of your chemicals requirement from Single Kilogram for clinical trials to Multi-metric ton commercial quantities. You can always trust ETA to help you get your products to market faster by adding real value to your development process.
Confidentiality of proprietary information is strictly observed, If necessary a secrecy agreement is signed in advance.

R&D center
ETA's R&D center is located in Shanghai Zhangjiang Hi-Tech Park , China. Staffed with 2 Ph.D.from USA and 5 M.S. chemists in China, ETA is equipped with HPLC, GC, and other analytical instruments. Tests can be done on IR, GC/MS, LC/MS and 400NMR at the SIOC through contract. Our fully equipped research laboratories are dedicated to the route discovery, validation, and process development.
Once the projects come into our R&D center, our highly experienced chemists will conduct quick initial evaluation and offer you our proposal for further activities.
From first batch sample submission to pilot scale up and chemistry validation, we emphasize on the speed without compromising the quality. Our well-trained analytical chemists are responsible for method development supporting the process development team.Reactions can be carried out in up to 50L glass-lined vessels. High-pressure hydrogenation vessels and autoclaves are also available up to 10L.
