Xanomeline IntermediatesDudley's 3-(4-hexyloxy-1,2,5-Thiadiazol-3-yl)-1-methylpyridine iodide is a bright yellow crystalline powder and a high-purity quaternary ammonium salt pharmaceutical intermediate. As a direct precursor for the synthesis of the M1/M4 muscarinic receptor agonist xanomeline, this product plays a central role in the production chain of drugs for schizophrenia and Alzheimer's disease. We employ a precise quaternization process, strictly controlling the reaction endpoint to ensure extremely high conversion rates and purity, yielding a high-quality active pharmaceutical ingredient (API) in a single reduction step

Applications
3-(4-hexyloxy-1,2,5-thiadiazol-3-yl)-1-methylpyridine iodide (CAS: 131988-19-7) is the highest-order intermediate in the Xanomeline synthetic route.
This product can be directly converted into Xanomeline (the active ingredient of KarXT/Cobenfy) by selective reduction with sodium borohydride (NaBH4) or other reducing agents.
As it is the final intermediate step before the active pharmaceutical ingredient (API), its purity directly determines the impurity profile of the final API. Therefore, high-end pharmaceutical companies have extremely stringent quality requirements for this product.
It can be used to develop other quaternary ammonium salt derivatives targeting muscarinic receptors or as a cationic probe tool.
