CHEMOS supports heterocyclic building-block synthesis for medicinal chemistry, discovery chemistry, and process-development programs. Diverse heterocycles : substituted 5-, 6-, and 7-membered N/O/S heterocyclic intermediates. Custom synthesis : route design from substituted precursors or suitable starting materials. Cross-coupling chemistry : C-N, C-C, C-O, and related bond-forming steps can be evaluated by substrate. Route optimization : impurity control, purification strategy, and robust reaction-condition screening. Scale-up support : batch-size planning after feasibility and safety review.
