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
Di-deuterated linoleic acid ethyl ester Di-deuterated linoleic acid ethyl ester Di-deuterated ethyl linoleate (also known as RT001; Di-deuterated linoleic acid ethyl ester, 11,11-D2-Ethyl Linoleate, Ethyl 11,11-D2-Linoleate) is an experimental, orally-bioavailable synthetic deuterated polyunsaturated fatty acid (PUFA), an isotopologue of an essential omega-6 PUFA, linoleic acid. The deuterated compound, while identical to natural linoleic acid, is resistant to lipid peroxidation which makes studies of its cell-protective properties worthwhile. Investigations of 11,11-D2-Ethyl linoleate (RT001) are being conducted in several neurological indications, including Friedreich’s ataxia and Infantile Neuroaxonal Dystrophy. A double-blind comparator-controlled Phase I/II clinical trial sponsored by Retrotope and Friedreich’s Ataxia Research Alliance was conducted to determine
