In 1993, we founded CHESS as a service provider conducting exclusive custom research projects mainly for the Pharmaceutical Industry. Our experience in this field adds up to more than 30 man-years and covers a wide range of modern Organic Chemistry. Since 1997, we expanded our business to the synthesis of fine chemicals. Our focus lies on building blocks mainly for use in medicinal chemistry. The very most of these compounds are synthesised in our laboratories in Germany. On the one hand, we are specialised in derivatives of substructures such as Piperazine, Piperidine and Pyrrolidine. On the other hand, one can also find special Alkylating Agents, Amines and Carboxylic Acid derivatives in our product listing. Some of those structures can be understood as simple but also exclusive Amino Acid derivatives. Our main capital is a motivated team of 6 skilled chemists (all phd) and 3 technicians. We work together to develop exclusive building blocks that may help our customers to achieve their goals easier and faster. Our Standard:? Affordable quality: "usually >98%"? Short delivery times, usually "ex stock"? Uncomplicated business relation:"chemists for chemists"
