Description

Obidoxime Chloride CAS NO 114-90-9 is a quaternary ammonium oxime salt primarily recognized as a potent reactivator of acetylcholinesterase inhibited by organophosphate compounds. Its core value proposition lies in its critical role as an antidote in the treatment of poisoning from certain pesticides and nerve agents, making it an essential component of emergency medical and defense preparedness protocols. This compound is needed by pharmaceutical manufacturers, government defense agencies, and research institutions focused on toxicology and medical countermeasures.

Application

• Pharmaceutical Antidote: Key active pharmaceutical ingredient (API) in injectable formulations for the treatment of organophosphate poisoning.
• Medical Countermeasures: Essential component in emergency response kits and stockpiles for military and civilian defense against chemical warfare agents.
• Veterinary Medicine: Used in treatments for pesticide poisoning in animals.
• Toxicological Research: Serves as a standard and research chemical in studies investigating cholinesterase reactivation mechanisms and efficacy.
• Reference Standard: Utilized in analytical laboratories for method development and quality control testing of antidote formulations.

Quality Control

Our Obidoxime Chloride is manufactured under strict quality systems to ensure it meets the exacting standards required for pharmaceutical and research applications. Each batch is subjected to comprehensive analytical testing, including identification, purity assay, and impurity profiling. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to guarantee traceability and compliance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at 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 performance.
