For almost two decades, our expert chemists have been designing synthetic routes for new or complex compounds, labeled with stable isotopes, for different applications to support our customers worldwide. Alsachim provides custom synthesis service to meet to your specific requirements and to support your research programs. Our aim is to provide you the best custom synthesized standard to satisfy your needs and enable you to reach the most accurate results for your LC-MS/MS analysis.

Let us know about your specifications !

Bringing our know-how and skills, we listen to your needs and requirements, and we carry out a R&D process to propose a synthetic route in line with the entire project, offering the best solution for strategic isotopes positioning (13C, 15N, 2H, 18O, 34S) with non-exchangeable isotopes position.

Our expert chemists' teams will design the optimal compound with single or multi labeling, to perform reliable quantitative LC-MS/MS measurements with maximized sensitivity; meaning it has greater isotopic mass purity and greater labelling stability allowing CP-MAS and NMR studies.

We excel at providing high quality products (high purity level with no unlabeled compound detected). Purity levels are determined by HPLC-UV-MS analysis, mass spectrometry, 1H, 13C, 19F, 31P NMR spectroscopy and provided with a complete Certificate of Analysis.

We aim to build long-term client relationships by listening, understanding, and meeting our client's needs in a reasonable time. Throughout the process, we keep you informed by providing regular updates on your customized synthesis project.

Alsachim offers custom synthesis of stable isotopically labelled standards including:

How we proceed?

Each project is analyzed by our custom synthesis experts, who define the optimum synthetic route to meet specifications and provide a customized solution.
