Description

Propionylthiocholine Chloride is a high-purity biochemical reagent and a critical substrate for the detection of cholinesterase activity. Its primary value lies in its specificity and reactivity, enabling precise enzymatic analysis essential for research and diagnostic applications. This compound is vital for pharmaceutical R&D, clinical diagnostics, and academic research in neurochemistry and toxicology.

Application

• Primary substrate for the colorimetric and spectrophotometric assay of cholinesterase (ChE) and butyrylcholinesterase (BuChE) activity.
• Essential reagent in clinical diagnostic kits for monitoring liver function, pesticide exposure, and neuromuscular disorders.
• Used in neuropharmacology research to study the effects of drugs, toxins, and nerve agents on the cholinergic system.
• Key component in biochemical research for enzyme kinetics studies and inhibitor screening.
• Applied in environmental toxicology for detecting organophosphate and carbamate pesticide residues.
• Utilized in the development and quality control of acetylcholinesterase-based biosensors.
