Description

Parapenzolate Bromide is a quaternary ammonium anticholinergic compound with significant pharmacological activity. This substance is valued for its potent and selective action on muscarinic receptors, making it a critical intermediate in advanced pharmaceutical synthesis. It is primarily utilized by research institutions and pharmaceutical manufacturers developing treatments for gastrointestinal and genitourinary disorders, where precise chemical control is paramount.

Application

• Pharmaceutical Intermediate: A key building block in the synthesis of antispasmodic and antisecretory medications.
• Research & Development: Used in pharmacological studies to investigate muscarinic receptor antagonism and its therapeutic effects.
• Active Pharmaceutical Ingredient (API) Synthesis: Serves as a precursor in the manufacturing of final drug formulations targeting smooth muscle spasms.
• Biochemical Research: Employed as a reference standard or tool compound in neuropharmacology and autonomic nervous system research.
• Contract Manufacturing: Supplied to CDMOs (Contract Development and Manufacturing Organizations) for custom synthesis projects.

Quality Control

Our Parapenzolate Bromide is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot is subjected to comprehensive analytical testing, including identification, assay, and impurity profiling, to meet the stringent requirements of pharmaceutical R&D and production. A detailed Certificate of Analysis (COA) is provided with every shipment, documenting compliance with agreed specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed to prevent moisture absorption, which can affect stability and handling properties.
