Olmesartan Impurity 52 is chemically 1H-​Tetrazole, 5-​[4'-​(bromomethyl)​[1,​1'-​biphenyl]​-​2-​yl]​-​1-​(triphenylmethyl)​-; 5-[4'-(Bromomethyl)[1,1'-biphenyl]-2-yl]-1-(triphenylmethyl)-1H-tetrazole; 1-Triphenylmethyl-5-[4'-(bromomethyl)biphenyl-2-yl]tetrazole; 4-Bromomethyl-2'-[N-triphenylmethyl-1H-tetrazol-5-yl]biphenyl; 4-[2'-(N-Triphenylmethyltetrazol-5-yl)phenyl]benzyl bromide; 4'-Bromomethyl-2-(1-triphenylmethyltetrazol-5-yl)biphenyl; 4'-Bromomethyl-2-(1-trityl-1H-tetrazol-5-yl)biphenyl; 4'-Bromomethyl-2-(N-trityl-1H-tetrazol-5-yl)biphenyl; 5-(4'-Bromomethylbiphenyl-2-yl)-1-trityl-1H-tetrazole; 5-[4'-(Bromomethyl)biphenyl-2-yl]-N-(triphenylmethyl)tetrazole; N-Triphenylmethyl-5-[2-(4'-bromomethylbiphenyl)]tetrazole; N-Triphenylmethyl-5-[4'-(bromomethyl)biphenyl-2-yl]tetrazole; [2'-(1-Trityl-1H-tetrazol-5-yl)biphenyl-4-yl]methyl bromide; [2'-(N-Trityltetrazol-5-yl)biphenyl-4-yl]methyl bromide; [2'-(Triphenylmethyl-1H-tetrazol-5-yl)biphenyl-4-yl]methyl bromide. Olmesartan Impurity 52 is supplied with detailed characterization data compliant with regulatory guideline. Olmesartan Impurity 52 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 Olmesartan.

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.
