呋喃唑酮属硝基呋喃类抗菌药,虽然近年其应用呈下降趋势,但因价格低廉,疗效确切,仍有很大的市场,其含量的测定方法为紫外分光光度法,但由于呋喃唑酮在合成过程中的杂质(主要为硝基呋喃甲醛二乙酯,下称二乙酯)在367nm处有很强的吸收,因此很难反映呋喃唑酮的真实含量。我们采用高 Furazolidone is a nitrofurane antibacterial drug, although its application is declining in recent years, but due to low prices, the exact effect, there is still a large market, the determination of the content of UV spectrophotometry, but due to furazolidone in the synthesis process Of the impurities (mainly nitrofuraldaldehyde diethyl, hereinafter referred to as diethyl ester) at 367nm at a strong absorption, it is difficult to reflect the true content of furazolidone. We use high
