                          For isopropyl thiophenol is a kind of important pharmaceutical intermediates in organic synthesis is often used as hydroxyl protectant, and widely used synthetic light initiator and anti-inflammatory drugs. By the synthesis of benzoic acid of isopropyl benzene sulfide, is the UV light curing initiator and anti-inflammatory drug intermediates; By the synthesis of adjacent isopropyl sulfur impurity anthracene ketone (ITX) light initiator, excellent performance, high sensitivity, especially suitable for deep curing

                    Xiang ying eagle analysis technology co., LTD. By XiangyingGC7990plus capillary gas chromatography, with hydrogen flame detector, the capillary chromatographic column separation of isopropyl thiophenol, isopropyl benzene thiophenol, between adjacent isopropyl thiophenol and isopropyl thiophenol disulfide, with 1, 4-trichlorobenzene - trichlorobenzene as internal standard, has carried on the quantitative analysis of the internal standard method. The four compounds in 51.2 to 1, 280.5, 1.8 ~ 46.0, 2.1 ~ 53.0 and 53.0 ~ 51.0 mg/L mass concentration has a linear response range, detection limit were 0.43, 0.45, 0.53, 0.45 mg/L, precision are 0.07%, 1.58%, 2.32% and 0.07% respectively, the average recovery was 98% ~ 101%. The method is simple operation, good precision, good linear, high recovery rate, can easily in practical application.

                        对异丙基苯硫酚是一种重要的医药中间体,在有机合成中常用作羟基保护剂,并广泛用于光引发剂及抗炎药物的合成。由其合成的邻苯甲酸对异丙基苯硫醚,是UV线光固化引发剂及抗炎药物的中间体;由其合成的邻异丙基硫杂蒽酮(ITX)光引发剂,性能优异,感光度高,尤其适用于深层固化
                      滕州市翔鹰分析技术有限公司采用XiangyingGC7990plus毛细管气相色谱法,以氢火焰检测器、毛细管色谱柱分离了对异丙基苯硫酚、间异丙基苯硫酚、邻异丙基苯硫酚和对异丙基苯硫酚二硫化物,以1,2,4-三氯苯为内标物,进行了内标法定量分析。这4个化合物分别在51.2~1 280.5、1.8~46.0、2.1~53.0、2.0~51.0 mg/L质量浓度范围内呈线性响应,检出限分别为0.43、0.45、0.53、0.50 mg/L,精密度分别为0.07%、1.58%、2.32%、2.18%,平均回收率为98%~101%。该方法操作简单、精密度好、线性好、回收率高,可方便地进行实际应用。
