Endotherm Services

 We provide custom synthesis of high-value rare research chemicals in the following areas


Medicinal Chemistry

Drug discovery and development: Screening-compounds, libraries, intermediates, fluorescent dyes, hit-to-lead-studies and lead optimizations by chemical structural modifications.


Clinical Chemistry

Reference standards of active pharmaceutical ingredients and biomarkers, along with their metabolites, including labeling with 2H, 13C or 15N, mainly for their application in LC-MS/MS-based assays; conjugates of antigenes and intermediates for the discovery of specific antibodies for immunological assays.



Reference standards, impurities, metabolites, intermediates and laboratory samples of active pharmaceutical ingredients


Finally, we can support our customers for process research purposes towards the manufacture of various chemical compounds in a wide range of applications (pharma-, crop science- nutrition- and cosmetics-industry)


Your benefits / 5 good reasons:


1. Inhouse-made compounds („Made in Germany“):

In our state-of-the-art laboratory in the Science Park 2 on the campus of the Saarland University (Germany) our highly qualified team, consisting of experienced Ph.D. organic chemists and technicians, all compounds are made inhouse (no trading), thus assuring quality, reliability and deadlines.

2. Scientific Excellence:

By numerous publications (articles in high-impact peer-reviewed journals, contributions to books, patents) und participation in various excellence-projects, funded by the EU-Commission, our compentence and experience in the synthesis of bioactive compounds, gained within more than 30 years, can thus convincingly be demonstrated.

3.Efficient Communication:

Beginning with an initial inquiry, all communication related to relevant chemical structures, price, quantity and deadlines, further the delivery of the requested compounds in the required quality and quantity, and finally reporting and invoicing – all this can be communicated with just one project manager in our organization. This assures reliability, confidentiality, trustworthiness, and pragmatic negotiations.

4. Quality Management:

All processes and documents underly stringent requirements of an implemented quality management system according ISO 9001, which is consistently applied, internally and externally monitored and continuously improved.

5. Innovative for already 30 years

Benefit from our expertise in the synthesis of bioactive compounds. Already since anno 1987, our CEO Lars Kattner is involved with the development of synthetic strategies and their application to the synthesis of complex bio-active molecules in the life sciences.
