该化合物是用于乳化过程的分析化学,特别是用于确定钙和镁等金属离子的金属离子,主要优点在于它具有很高的选择性和敏感性,因为它在形成稳定的复合物时具有双价加速度,从而能够在EDTA乳房中精确检测端点.该化合物在等值点显示出从红色到蓝色的强烈颜色转变,确保了可靠和可复制的结果.其水溶液的稳定性和与一系列pH条件的兼容性进一步提高了其定量分析的效用. Mordant Black 17广泛用于水硬度测试和工业质量控制应用.
专利号:US-2004266699-A1 优先权日:2001-10-04 标 题 :Flavonoid compounds capable of modifying the dynamic and/or physical state of biological membranes and to stimulate the endogenous synthesis of stress proteins in eukaryotic cells, relative synthesis and their use 发明人:PORTA AMALIA 摘要:The invention relates to flavonoids compounds of formula (I) and (II) capable of modifying the dynamic and/or physical state of biological membranes and to stimulate the endogenous synthesis of stress proteins in eukaryotic cells. Such compounds are molecules of plant origin or synthetic. The invention also describes a method to identify, purify and chemically synthesize such flavonoid compounds and test their efficacy through their capacity to stimulate the transcription of stress genes and as a consequence, to interact with biological membranes with alteration of their relative physical state. Such compounds and corresponding pharmaceutically acceptable derivatives and/or salts have applications in the areas of pharmaceuticals, more specifically in cosmetics and dermatology, for all those afections related to an alteration of the expression of stress genes.
