自异菸醯肼被介绍为治疗肺结核之药品以来,寻求一鉴定该药品之方法,成为必需之条件。Canb(?)ck 氏以溴及碘氧化该化合物为研究此问题之根据,于最近发表一种用碘之标准溶液以氧化之法。如以溴定量法(Bromimetric Assay)之手续,鉴定纯原料及药片时,所得结果颇为一致。故本报告即就上述两法作一比较。(该二法详见于 Since isoniazid has been introduced as a drug for the treatment of tuberculosis, the search for a method of identifying the drug has become a prerequisite. Canb (?) Ck’s bromine and iodine oxidation of the compound is the basis of this issue, recently published a standard solution of iodine oxidation. As with the bromometric method (Bromimetric Assay) procedures, identification of pure raw materials and tablets, the results obtained are quite consistent. Therefore, this report compares these two laws. (The two methods in detail
