Appliction
Characteristic of this product is white or kind of white powder;Odourless;Easy to lead wet;Aqueous solution show dextral light.The product easy to dissolve in water, in ethanol, ether, acetone, or almost insoluble in chloroform.Identify
(1) take this product for about 10 mg, add water 1 ml dissolves, add 2 ml of hydrochloric acid solution (9-100), heated in water bath for 10 minutes, with 2 ml of 8% sodium hydroxide solution and 2% acetyl acetone solution 1 ml, water bath heating in 5 minutes. After cooling, add to dimethyl amino benzene formaldehyde test solution 1 ml, namely the cherry red.
(2) apply the product standard and neomycin, respectively made each 1 ml contains 20 mg of water solution.According to thin layer chromatography (TLC) test, 1 mu l learned these two solution, each point in the same silica gel H thin layer plate (silica gel h1.5o g 6 ml with 0.25% sodium carboxymethyl cellulose solution mixing plate), acetic acid with methanol - - acetone - 8.8% ammonium acetate solution (corresponding: 10:40:) as developing agent, unfolds, dry, dry in 110 ºC for 20 minutes, by hot spraying with 10% sodium hypochlorite solution, the thin layer plate on ventilation, cooling, a spray starch potassium iodide solution (0.5% starch solution contained 0.5 g of potassium iodide in the 100 ml), immediately.Show the main spots by color of test sample solution and location should be the same as the main mark of the standard solution.
(3) of this article show the identification of sulphate aqueous reaction.
