Cas no 1532-91-8 (4-Chloroisoquinoline)
4-Chloroisoquinoline is a heterocyclic aromatic compound featuring a chlorine substituent at the 4-position of the isoquinoline scaffold. This structure serves as a versatile intermediate in organic synthesis, particularly in pharmaceutical and agrochemical applications. Its reactive chlorine atom enables facile functionalization through cross-coupling reactions, nucleophilic substitutions, or metal-catalyzed transformations. The compound’s rigid bicyclic framework contributes to its utility in constructing complex molecular architectures. It is commonly employed in the development of bioactive molecules, including potential therapeutic agents targeting neurological or inflammatory pathways. High purity grades are available to ensure reproducibility in research and industrial processes. Proper handling under inert conditions is recommended due to its sensitivity to moisture and air.
