With their Clean Peptide technology, Sulfotools is revolutionizing the over 40-year-old process of chemical peptide synthesis, making it more sustainable and eco-friendly.

They offer an efficient, resource-conserving process with cost-savings up to 50%, compared to the state-of-the-art. With their proprietary Clean Peptide Technology, the so far required hazardous organic solvents can be completely replaced with water, and the excess of reagents can be minimized, finally combining sustainability with cost optimization. Sulfotools’ technology also includes an efficient purification system, a waste water treatment option, and for the first time ever, a real-time monitoring of the reaction progress is possible.

The basis of the Clean Peptide Technology was discovered by Sascha Knauer during his PhD thesis through a random experiment.

The Rhein-Main area (where their headquarters is situated) is one of the leading cluster regions in Germany for the chemical and pharmaceutical industry. A majority of the company’s potential customers are located there.
