试剂描述: 产品名称:Reichardt's dye 产品别名:2,6-二苯基-4-(2,4,6-三苯基吡啶);2,6-Diphenyl-4-(2,4,6-triphenyl-1-pyridinio)phenolate CAS号:10081-39-7 英文别名:Reichardt's dye 分子量:551.68 分子式:C41H29NO 纯度:90% 外观:见爱必信官网 保存方法:Store at room temperature,1 year. 描述: Reichardt's dye is a highly solvatochromic betaine dye used to determine solvent polarity. Solvatochromism of the dye results from a large reduction of the dipole moment and hydrogen bonding, as well as from the regulation of the mesomeric effect. In the presence of L-glutamic acid-derived peptide lipid with a benzyloxycarbonylated Gly headgroup, Reichardt's Dye in chlorobenzene was favored towards the more polar microenvironment of the peptide lipid in contrast to chlorobenzene , and a shift of color was observed. In a study of hydrophobic compounds, the dye was placed within polydendrimers to study the inner environment of the dendritic macro-molecular capsules. 应用:A solvatochromic betaine dye used to determine solvent polarity
