1,5-Dibromopentane (CAS No. 111-24-0) is a halogenated organic compound consisting of a five-carbon alkane chain with bromine (-Br) atoms at both ends. It is a key intermediate in organic synthesis, particularly in the production of polymers, pharmaceuticals, and specialty chemicals. Due to its bifunctional nature, it is commonly used in nucleophilic substitution and coupling reactions for the synthesis of macrocycles and heterocyclic compounds.
