MRT - Mono-Boc-Protection of Diamines

Mono-Boc-protected diamines are versatile building blocks for chemical synthesis. Their production is a lot more challenging than the simple reaction scheme might imply, because the Boc-anhydride reagent cannot differentiate between the two identical amino moieties in the substrate.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
