A quantitative method for the assay of phenol in ointments is described. The procedure involves the formation of a blue indophenol by reacting phenol with 2,6-dibromoquinone-4-chloroimide which can be measured spectrophotometrically. The method is accurate, and interference from other active ingredients (hydrocortisone and menthol) does not occur.
描述了一种测定软膏中苯酚的定量方法。该方法包括通过使苯酚与2,6-二溴醌-4-氯亚胺反应形成蓝色靛酚，然后可通过分光光度法进行测量。该方法准确，且不会受到其他活性成分（氢化可的松和薄荷醇）的干扰。
