3-(4-Fluorophenyl)thiophene-d4 is labelled 3-(4-Fluorophenyl)thiophene (F596255) which is an impurity of Canagliflozin (C175190), a sodium/glucose cotransporter 2 (SGLT2) inhibitor. Canagliflozin has been shown to dose dependently reduce calculated renal threshold for glucose excretion and increase urinary glucose excretion. Canagliflozin is a candidate for the treatment of type 2 diabetes and obesity. Molecular Formula: C10H3D4FS Molecular Weight: 182.25
