Chlorosulfonic acid is a strong sulfonation and sulfation reagent and is occasionally also used as a chlorinating agent. It is used in the production of detergents, dyes and ion exchange resins, but also in the production of agrochemicals, pharmaceutical active ingredients and other sulfonated compounds.

CABB is the largest European manufacturer of Chlorosulfonic acid and supplies global customers. CABB offers sulfonation and sulfation reactions in toll or custom manufacturing also with other reagents in a sustainable way.

The Pyridine Sulfur Trioxide Complex is an important reagent for mild sulfonations and sulfations and acts as a reagent for the Parikh-Doering oxidation of alcohols into aldehydes.

As a sulfonation and sulfation reagent PSS is mainly used in the synthesis of complex and sensitive molecules in pharmaceutical and agrochemical applications.

CABB is the leading manufacturer of Pyridine Sulfur Trioxide Complex of high purity. PSS can be regarded the standard reagent with good stability and high reactivity. Further sulfur trioxide amine complexes with different reactivity (like Trimethylamine SO₃ or N,N-Dimethylformamide SO₃) are available on request.

Sulfuryl chloride is a commonly used chlorination reagent for the chlorination of non-functionalised molecules. It shows a similar reactivity like chlorine but is somewhat more selective. As a liquid it can be easier handled than chlorine and can be transported. In some cases sulfuryl chloride is used as a SO₂Cl-building block.

CABB is a leading European manufacturer of sulfuryl chloride. In addition, CABB offers toll and custom manufacturing of chlorination reactions with various reagents in a sustainable way in its Verbund and Recycling System.

Thionyl chloride is a widely used transportable chlorination reagent for the chlorination of functionalised molecules like alcohols, carboxylic acids and sulfonic acids.

CABB is a leading European manufacturer of Thionyl chloride. In addition, CABB offers toll and custom manufacturing of chlorination reactions with various reagents in a highly efficient and sustainable way in its Verbund and Recycling System.
