Description

Oxybutynin Hydrochloride CAS NO 1508-65-2 is a high-purity anticholinergic pharmaceutical active ingredient. It is a critical component in the formulation of medications used to treat overactive bladder and urinary incontinence. This compound is essential for pharmaceutical manufacturers and research institutions developing antispasmodic therapies. We supply this API with a focus on stringent quality control and reliable global supply chains.

Application

• Pharmaceutical API: Primary active ingredient in prescription medications for overactive bladder (OAB) and neurogenic detrusor overactivity.
• Extended-Release Formulations: Used in the development of controlled-release tablets and transdermal delivery systems for improved patient compliance.
• Generic Drug Manufacturing: Serves as the key raw material for producing generic versions of antimuscarinic drugs.
• Clinical Research: Utilized in preclinical and clinical studies for new urological and antispasmodic treatments.
• Veterinary Pharmaceuticals: Potential application in formulations for urinary incontinence in animals.
• Reference Standard: Sourced by analytical laboratories for use as a high-purity chemical reference standard in quality testing.
