2-(4-fluorophenyl)-5-(2-methylbenzyl)thiophene

2-(4-Fluorophenyl)-5-(2-methylbenzyl)thiophene is a heterocyclic thiophene derivative featuring a 4-fluorophenyl substituent at the 2-position and a 2-methylbenzyl group at the 5-position. The fluorinated aromatic ring and methyl-substituted benzyl moiety confer distinct steric and electronic properties, diverging from the core structure of Canagliflozin by a methylene bridge replacement with thiophene. This impurity arises via nucleophilic aromatic substitution during synthetic pathways involving thienyl coupling. Serves as an HPLC reference standard for Canagliflozin impurity profiling.
