structure that contains atoms from at least two separate elements. Heterocyclic intermediates 
are present in many medications, including antibiotics, antivirals, and cancer treatments. 
Halogenated Compounds: In the production of pharmaceuticals intermediates typically 
employed as starting materials include halogenated compounds including chlorides, bromides, 
and iodides. They may add particular chemical characteristics or increase the final medication 
molecule's effectiveness. Compounds with an asymmetric carbon atom produce two mirror-
image forms (enantiomers) known as chiral intermediates. Pharmaceutical medications 
frequently need for particular stereochemistry, and the chiral intermediates are essential for
