ChemEast Laboratory Ltd was founded in 2008 based our 30 years experiences in the field of synthetic chemistry. We concentrate our work onto the development and production of new quinoline derivatives primarily. The result of this work we have more than 3000 quinoline derivatives in our catalogue. These intermediates are a broad range of novel building blocks for use in medicinal chemistry. Many compounds are available in gram scale from stock or we can synthesize them within 2 weeks. Larger quantities (up to 1-2 kgs) are also available on request. If you have a question, please do not hesitate to contact with us.
