Description

Propionylthiocholine Iodide is a high-purity organic salt primarily used as a critical substrate in enzymatic assays. This compound is essential for the accurate measurement of cholinesterase activity, a key parameter in biochemical research and toxicology. It is a vital reagent for researchers and quality control laboratories in the pharmaceutical, agrochemical, and diagnostic industries requiring precise enzyme kinetics data.

Application

• Primary substrate for cholinesterase enzyme assays, including acetylcholinesterase (AChE) and butyrylcholinesterase (BChE).
• Biochemical research for studying enzyme kinetics, inhibition, and reactivation mechanisms.
• Toxicology screening to detect and quantify exposure to organophosphate and carbamate pesticides.
• Diagnostic reagent development for clinical tests related to liver function and nerve agent exposure.
• Pharmaceutical development for in vitro evaluation of potential drugs targeting the cholinergic system.
• Quality control in industries manufacturing anticholinesterase agents or related compounds.
