| Manganese(II) chloride | Manganese(II) chloride. Uses: Manganese(II) chloride forms double salts with alkali metal chlorides when mixed in stoichiometric amounts. such double salts, which can decompose in water, may have compositions like kmncl3 or k2mncl4. manganese(II) chloride forms adducts with ammonia, hydroxylamine and many other nitrogen compounds. many adducts are stable at ordinary temperatures. examples are mncl2 6nh3 and mncl2 2nh2oh. an aqueous solution can readily undergo double decomposition reactions with soluble salts of other metals, producing precipitates of insoluble salts of mn(II) or other metals. Group: Electrolytes. Alternative Names: manganese-chloride; Manganese (II) chloride; CTK0H1763; Manganese(II) chloride, 97%; AKOS015904562; ACMC-20akkt; DTXSID9040681; TR-037793; Manganese(II) chloride, 99+%, anhydrous, -80 mesh; Manganous chloride,anhydrous.

| Murexide | REAGENT (NH4C8H4N5O6, or C8H5N5O6·NH3), also called ammonium purpurate or MX, is the ammonium salt of purpuric acid. It may be prepared by heating alloxantin in ammonia gas to 100°C, or by boiling uramil (5-aminobarbituric acid) with mercury oxide. W.N. Hartley found considerable difficulty in obtaining specimens of REAGENT sufficiently pure to give concordant results when examined by means of their absorption spectra, and consequently devised a new method of preparation for REAGENT. In this process alloxantin is dissolved in a large excess of boiling absolute alcohol, and dry ammonia gas is passed into the solution for about three hours. The solution is then filtered from the precipitated REAGENT, which is washed with absolute alcohol and dried. The salt obtained in this way is in the anhydrous state. It may also be prepared by digesting alloxan with alcoholic ammonia at about 78°C; the purple solid so formed is easily soluble in water, and the solution produced is indistinguishable from one of REAGENT.REAGENT in its dry state has the appearance of a reddish purple powder, slightly soluble in water. In solution, its color ranges from yellow in strong acidic pH through reddish-purple in weakly acidic solutions to blue-purple in alkaline solutions. The pH for titration of calcium is 11.3.Justus von Liebig and Friedrich Wöhler in Giessen, Germany, had investigated the purple product, REAGENT, obtained from snake excrement in the 1 | |
| Diethylpyrocarbonate (DEPC) | DEPC is a strong nuclease inhibitor, utilizing a mechanism which modifies His and Tyr residues in proteins. Used as a RNase and DNase inhibitor for Molecular Biology solutions. DEPC is a chemical use to inactivate RNase enzymes and is sensitive to moisture and pH. It decomposes at 155°C, to ethanol and carbon dioxide in aqueous solution. DEPC is also sensitive to ammonia, which causes decomposition to urethane, a possible carcinogen. Group: Biochemicals. Alternative Names: Diethyloxydiformate; Ethyloxyformic acid anhydride; Diethyl dicarbonate; DEP; DEPC; EC 216-542-8. Grades: Molecular Biology Grade. CAS No. 1609-47-8. Pack Sizes: 25g, 50g, 100g.
