HPLC Method for Neostigmine methylsulfate, Norneostigmine on Primesep 100 by SIELC Technologies
High Performance Liquid Chromatography (HPLC) Method for Analysis of Neostigmine methylsulfate, Norneostigmine.
Neostigmine methylsulfate is a drug with the chemical formula C13H22N2O6S. It is primarily used to reverse effects of non-depolarizing neuromuscular blocking agents after surgery. It works through inhibiting the enzyme acetylcholinesterase, preventing the breakdown of the neurotransmitter acetylcholine, which leads to a buildup of it at nerve endings, which stimulates muscle contractions.
Neostigmine methylsulfate, Norneostigmine can be retained and analyzed using the Primesep 100 stationary phase column. The analysis utilizes an isocratic method with a simple mobile phase consisting of water and acetonitrile (MeCN) with a sulfuric acid buffer. Detection is performed using UV.
