About N,N Carbonyl diimidazole (CDI)

Our N,N-Carbonyldiimidazole (CDI) is a high-purity white crystalline reagent engineered to activate carboxylic acids for nucleophilic substitution. Acting as a safer, solid alternative to highly toxic phosgene, CDI facilitates clean reactions by releasing only CO₂ and imidazole as relatively innocuous by-products. In 2...
