The Uses of 2-Ethylpyridine

2-Ethylpyridine is used to study its effect on the proliferation and survival of human umbilical vein endothelial cells (HUVECs), HMVECs from lung, and NIH 3T3 cells. 2-Ethylpyridine linked with silica is a popular stationary phase for chiral and achiral separations in supercritical fluid chromatography.
