Synthesis of compounds on solid-phase supports became quite popular in the late 1990s and, though interest might have waned a little more recently, there may still be a demand for it in some establishments. If monitoring reactions carried out on resins is what is required, then a magic angle spinning (MAS) probe is the only way to go.
