N-Trityl Losartan Isomer is chemically 2-Butyl-5-chloro-1-[p-(2-(triphenylmethyl)-2H-tetrazol-5-ylphenyl)benzyl] imidazole-4-methanol . It is also known as Losartan Isomer N2-Trityl Impurity. N-Trityl Losartan Isomer is supplied with detailed characterization data compliant with regulatory guideline. N-Trityl Losartan Isomer can be used for the analytical method development, method validation (AMV), Quality Controlled (QC) application for Abbreviated New Drug Application (ANDA) or during commercial production of Losartan.

The product can be used as reference standards and further traceability against pharmacopeial standards (USP or EP) can be provided based on feasibility. SynZeal products are for analytical purpose only and not for human use.
