Description

Obidoxime is a bis-pyridinium oxime compound primarily recognized as a potent reactivator of acetylcholinesterase inhibited by organophosphorus compounds. This makes it a critical component in the formulation of antidotes for nerve agent and organophosphate pesticide poisoning. It is essential for manufacturers in the pharmaceutical and defense industries, as well as for research institutions focused on toxicology and medical countermeasures. Our supply ensures high purity and reliability for these demanding applications.

Application

• Active Pharmaceutical Ingredient (API) in antidote formulations for organophosphate poisoning.
• Key component in emergency medical kits for military and first responder personnel.
• Research chemical for studying acetylcholinesterase reactivation mechanisms.
• Reference standard in analytical and forensic toxicology laboratories.
• Intermediate in the synthesis of advanced therapeutic agents targeting neurotoxicity.
• Formulation ingredient for investigational drugs in pre-clinical and clinical studies.

Quality Control

Our Obidoxime is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing to ensure identity, purity, and consistency, meeting the stringent requirements for pharmaceutical research and development. A detailed Certificate of Analysis (COA) is provided with every shipment, documenting key parameters such as assay, related substances, and residual solvents.

Storage

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