制备方法与用途

化学性质
纯品为淡黄色针状结晶（染料常为黄色或黄褐色粉末）。熔点为139-140℃，相对密度为1.211。它不溶于水，易溶于丙酮，并能溶解在乙醇、乙酸乙酯、乙酸和沸苯中。本品有毒性，极易通过皮肤吸收引起中毒，但能迅速随尿液排出。

用途
红色基B主要用于棉纤维染色、棉布印花以及黏胶纤维、蚕丝和涤纶的染色。它能够与色酚AS、AS-D偶合以获得更深的红色调，偶合能力强且偶合速度较慢。此外，它也被用于制造快色素，如快色素金黄2G、快色素枣红IB和快色素枣红GG等。

生产方法
方法1：使用邻乙酰氨基苯甲醚为原料，经过硝化和水解得到所需产物。 方法2：以邻甲氧基苯胺为原料，先进行对甲苯磺酰氯酰化处理，再经硝化和水解最终获得目标产品。

  An easy operable method of detecting phosphatase which comprises a step for the production of a dye to obtain an azo dye by the reaction of phosphatase in a tissue or cell or on chromosome with a 2'-naphthol AS phosphate, e.g. 3-hydroxy- N-2-biphenyl-2-naphthalenecarboxamide phosphate ester, followed by the reaction between the 2'-naphthol AS phosphate with a diazonium salt; an excitation step for the irradiation of excited light to the azo dye; and a detection step for the detection of fluorescence which is emitted upon irradiation of the excited light. The fluorescence is intense and lasts for a long time.

  Compositions and methods are disclosed for use in the analysis and quantitation of conjugated and unconjugated bilirubin in patient or other samples. The compositions have the general formula: 1 wherein: R 1 and R 2 are independently selected from alkyl and aryl, R 3 and R 4 are independently selected from hydrogen, alkyl, alkenyl, tauryl, aryl, and glucoronyl, and R 5 , R 6 , R 7 , R 8 , R 9 and R 10 are each independently selected from hydrogen and alkyl, and are resistant to oxidation, as occurs in bilirubin upon exposure to light and air. These properties make them ideal for use in calibration and control solutions for use in medical and research bilirubin analysis, or other applications where stable reagents for bilirubin analysis is desirable.
