Description

Mestinon CAS NO 101-26-8 is a high-purity pharmaceutical active ingredient, chemically known as pyridostigmine bromide. This compound is a reversible cholinesterase inhibitor, which is critical for managing neuromuscular transmission. It is primarily required by pharmaceutical manufacturers and research institutions for the production of medications and advanced clinical studies. Our supply ensures the stringent quality and consistency demanded by the global healthcare sector.

Application

• Pharmaceutical Manufacturing: Primary active ingredient in tablets and injectables for the treatment of myasthenia gravis.
• Neuromuscular Research: Used in preclinical and clinical studies to investigate cholinergic pathways and neuromuscular junction disorders.
• Antidote Formulation: A key component in nerve agent antidote kits due to its protective action against certain organophosphates.
• Veterinary Medicine: Employed in veterinary practices for managing similar neuromuscular conditions in animals.
• Reference Standard: Serves as a certified reference material (CRM) for quality control and analytical method development in laboratories.
