Description

Emepronium CAS NO 27892-33-7 is a quaternary ammonium compound with significant pharmacological activity. This compound is valued for its anticholinergic and antimuscarinic properties, making it a key intermediate in the synthesis of specialized pharmaceutical agents. It is primarily required by pharmaceutical R&D departments and fine chemical manufacturers for developing urological and gastrointestinal therapeutics.

Application

• Pharmaceutical Intermediate: A critical building block in the synthesis of antispasmodic and urinary antimuscarinic drugs.
• Active Pharmaceutical Ingredient (API) Synthesis: Used in the manufacturing process of APIs targeting overactive bladder and related conditions.
• Biochemical Research: Serves as a reference standard and a tool compound in pharmacological studies of muscarinic receptor antagonists.
• Fine Chemical Production: Employed in custom synthesis and contract manufacturing for specialized medicinal chemistry projects.
• Veterinary Medicine Development: Potential use in formulating treatments for urinary incontinence in animals.

Quality Control

Our Emepronium is produced under strict quality management systems. Each batch undergoes comprehensive analytical testing, including identification, purity assay, and impurity profiling, to ensure it meets the stringent requirements for pharmaceutical intermediates. Certificates of Analysis (COA) detailing all test results are available upon request to support your regulatory and quality assurance needs.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic (moisture-sensitive) nature, the container should be kept in a cool, dry place with controlled humidity. Recommended long-term storage temperature is 2-8°C. Allow the container to reach room temperature before opening to minimize moisture ingress.
