Chemical & Agrochemical Synthesis · 25 products

Catalysts, intermediates and reagents for fine chemical and agrochemical synthesis

Fine chemical and agrochemical manufacturers use our phase transfer catalysts — TEBAC, TBAB, benzyl tributyl ammonium chloride and the triphenyl phosphonium salts — to run alkylation, substitution and Wittig chemistry, alongside intermediates such as diphenyl acetonitrile and reagents such as sodium metal and iodine.

Share the reaction or the specification you work to — assay, moisture and halide limits matter for most catalysts — and we will confirm the right grade before quoting. Reactive and dangerous goods are packed and shipped under the agreed handling arrangements.
