Proposals for the pharmacopeia: opium and its preparations was written by Carlassare, Mario. And the article was included in Bollettino Chimico Farmaceutico in 1982.SDS of cas: 2451-01-6 This article mentions the following:
Changes in the Italian Pharmacopeia methods for anal. of opium, laudanum, and tablets containing K guaiacolsulfonate [1321-14-8], Na benzoate [532-32-1], terpin hydrate [2451-01-6], and Dover’s powder (morphine [57-27-2], emetine [483-18-1], and camphor) are proposed. Qual. color tests for meconic acid [497-59-6] and morphine in opium are described, together with a titrimetric method for measuring morphine and a simple TLC method for estimating morphine, papaverine [58-74-2], and codeine [76-57-3] in opium are given. For laudanum, color tests for morphine and meconic acid, and TLC estimation and determination of morphine (as for opium) are proposed. For the tablets, color tests are given for identification of K, benzoate, guaiacolsulfonate, terpin, and morphine, and a flame test for Na. A TLC method for morphine, codeine, papaverine and emetine, and quant. methods for Na benzoate (titrimetry) and K guaiacolsulfonate (colorimetry) are included for the tablets. In the experiment, the researchers used many compounds, for example, rel-(1s,4s)-4-(2-Hydroxypropan-2-yl)-1-methylcyclohexanol hydrate (cas: 2451-01-6SDS of cas: 2451-01-6).
rel-(1s,4s)-4-(2-Hydroxypropan-2-yl)-1-methylcyclohexanol hydrate (cas: 2451-01-6) belongs to alcohols. Alkyl halides are often synthesized from alcohols, in effect substituting a halogen atom for the hydroxyl group. Under carefully controlled conditions, simple alcohols can undergo intermolecular dehydration to give ethers. This reaction is effective only with methanol, ethanol, and other simple primary alcohols.SDS of cas: 2451-01-6
