Description

(R)-Oxybutynin Chloride CAS NO 119618-21-2 is the single enantiomer form of the antimuscarinic agent oxybutynin, specifically the (R)-enantiomer. This high-purity chiral intermediate is critical for the development and manufacturing of enantiomerically pure active pharmaceutical ingredients (APIs) targeting overactive bladder and related conditions. It is primarily required by pharmaceutical R&D laboratories, process chemists, and manufacturers engaged in the synthesis of advanced therapeutics where stereochemical purity is paramount for efficacy and regulatory approval.

Application

• Pharmaceutical Intermediate: Key chiral building block for the synthesis of enantiopure (R)-oxybutynin API.
• Research & Development: Used in pharmacological studies to investigate the specific activity and metabolic profile of the (R)-enantiomer.
• Process Chemistry: Serves as a reference standard and starting material for developing and scaling up stereoselective synthesis routes.
• Analytical Standard: Employed as a high-purity standard for HPLC, chiral chromatography, and other analytical methods for quality control.
• Drug Discovery: Utilized in medicinal chemistry programs for creating new derivatives or prodrugs with improved selectivity.
