Sildenafil EP Impurity F, chemically known as N-Desmethyl Sildenafil (CAS 160415-92-7), is a critical reference standard derived from the oxidative degradation of sildenafil. Its molecular formula is C22H29N7O4S, serving as an essential impurity marker for pharmaceutical quality control.
Strictly store under inert atmosphere at -20°C to prevent degradation. Handle only in certified laboratories using appropriate PPE due to potential toxicity and mutagenic risks associated with nitrosamine precursors.
