Losartan Bromo N1‑Trityl Impurity is a process-related intermediate in the synthesis of Losartan. It arises when the tetrazole moiety is protected with a trityl group and the biphenyl intermediate carries a bromomethyl substituent. While it has no therapeutic use, it is important in pharmaceutical manufacturing as a reference standard for impurity monitoring, helping ensure the final Losartan product meets purity and safety specifications.
