Potassium ethyl xanthate Potassium ethyl xanthate Potassium ethyl xanthate (KEX) is an organosulfur compound with the chemical formula CHCHOCSK. It is a pale yellow powder that is used in the mining industry for the separation of ores. Unlike the related sodium ethyl xanthate, the potassium salt exists as an anhydrous salt. Xanthate salts are prepared by the action of alkoxides on carbon disulfide. The alkoxide is often generated in situ from potassium hydroxide: Potassium ethyl xanthate is a pale yellow powder that is stable at high pH but rapidly hydrolyses at pH <9 at 25 °C. Unlike the sodium derivative, potassium xanthate crystallizes
N-Ethyl-3-piperidyl benzilate Schedule I controlled drugs. Radiolabelled versions of this drug have been used in scientific research to map the distribution of muscarinic acetylcholine receptors in the brain, however this drug has slightly lower binding affinity than the N-methyl analogue and so is less potent and not so widely used for this application. N-Ethyl-3-piperidyl benzilate "N"-Ethyl-3-piperidyl benzilate (JB-318) is an anticholinergic drug related to the chemical warfare agent 3-Quinuclidinyl benzilate. "N"-Ethyl-3-piperidyl benzilate is less potent and shorter acting than 3-quinuclidyl benzilate, but like 3-QNB its effects on the central nervous system predominate over peripheral effects. It produces deliriant and hallucinogenic effects similar
