Description

Atropine is a naturally occurring tropane alkaloid derived from plants of the Solanaceae family, such as deadly nightshade. This compound is a potent, competitive antagonist of muscarinic acetylcholine receptors, making it a critical agent for controlling involuntary muscle movements and secretions. It is an essential active pharmaceutical ingredient (API) and intermediate for manufacturers in the pharmaceutical, research, and agrochemical sectors. Our supply of Atropine CAS NO 83454-31-3 is characterized by high purity and reliable consistency to meet stringent industrial and regulatory requirements.

Application

• Pharmaceutical API: Primary use as an anticholinergic drug in ophthalmic solutions for pupil dilation and in pre-anesthetic medication to reduce secretions.
• Antidote Production: Key component in antidotes for organophosphate and carbamate pesticide or nerve agent poisoning.
• Research & Development: Used as a standard and tool compound in pharmacological, neurological, and biochemical research to study cholinergic systems.
• Agrochemical Intermediates: Serves as a precursor or model compound in the synthesis of certain pesticides and plant growth regulators.
• Veterinary Medicine: Employed in veterinary practices for similar antispasmodic and antisecretory indications in animals.
• Diagnostic Reagents: Utilized in the formulation of certain diagnostic kits and reagents for clinical testing.

Quality Control

Our Atropine is produced and tested under a strict quality management system. We can supply material compliant with various pharmacopoeial standards, including USP, EP, and BP monographs, depending on the grade. Every batch undergoes comprehensive analytical testing to confirm identity, purity, and impurity profiles. A Certificate of Analysis (COA) detailing all test results is provided with each shipment to ensure full traceability and compliance for our B2B clients.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed in a dry environment to prevent degradation. For long-term storage, consider using desiccants.
