Thermal Stability of the Guinea Green B Solution With Substrate and Its Application for the Detection of Cholinesterase Inhibitors

open access: yesAnalysis &Sensing, Volume 6, Issue 5, September 2026.
A Guinea Green B/butyrylthiocholine iodide solution offers a simple visual colorimetric approach for detecting cholinesterase inhibitors (neostigmine, VX, and A‐234). The aqueous formulation remains practically functional after 150 days at 60 °C, whereas the phosphate‐buffered variant rapidly degrades.
