Tolterodine Propylamine Impurity Racemate

Tolterodine Propylamine Impurity Racemate is a synthetic byproduct arising from the substitution of the 1,1-dimethylethyl group in Tolterodine with a propylamine moiety, resulting in a racemic mixture of piperidine derivatives. The compound features a benzodioxole core linked to a chiral piperidine ring bearing a propylamine side chain. This structural deviation from the parent drug leads to distinct chromatographic and spectroscopic properties. It serves as a critical HPLC reference standard for quantifying process-related impurities in Tolterodine formulations.
