《Separation and determination of biphenyl nitrile compounds by microemulsion electrokinetic chromatography with mixed surfactants》 was written by Gong, Suxuan; Bo, Tao; Huang, Lan; Li, Ke An; Liu, Huwei. SDS of cas: 74305-48-9 And the article was included in Electrophoresis on April 30 ,2004. The article conveys some information:
A mixture of six biphenyl nitrile compounds and three related substances with high hydrophobicity and similar structures was successfully separated by microemulsion electrokinetic chromatog. (MEEKC) within 30 min. The microemulsion system contained 100 mM sodium dodecyl sulfate (SDS), 80 mM sodium cholate (SC), 0.81% volume/volume heptane, 7.5% volume/volume n-butanol, 10% volume/volume acetonitrile, and 10 mM borate. The addition of SC, organic modifiers, sample preparation, and temperature all showed remarkable effects on the separation The capacity factor (k) was calculated by using dodecyl benzene as the marker for microemulsion, and the calculated partition coefficient log Po/w of the solutes was at 3.35-7.38. The log k values matched well with the log Po/w with a correlation coefficient of 0.96. The linear correlation coefficients of each compound between peak area and concentration were 0.996-0.998 with the repeatability relative standard deviation value < 1.2% for migration time and < 4.8% for peak area, and the highest theoretic plate number was > 586,000. MEEKC was compared with micellar electrokinetic chromatog. (MEKC) indicating that the former method is more suitable for this separation and can be used for the quality control of biphenyl nitrile compounds in the synthesis of liquid crystals. After reading the article, we found that the author used 4-n-Pentylphenyl-4-pentylbenzoate(cas: 74305-48-9SDS of cas: 74305-48-9)
4-n-Pentylphenyl-4-pentylbenzoate(cas: 74305-48-9) belongs to esters. Esters are more polar than ethers but less polar than alcohols. They participate in hydrogen bonds as hydrogen-bond acceptors, but cannot act as hydrogen-bond donors, unlike their parent alcohols. SDS of cas: 74305-48-9
