| Hazard Information | Back Directory | [Uses]
Oil Red EGN has been used to stain lipid droplets accumulated in cell during adipogenesis. | [Preparation]
O-Methylaniline diazotization, and 2,5-Dimethylbenzenamine coupling, product to diazotization, and Naphthalen-2-ol coupling. | [Biological Activity]
Oil Red EGN is widely used to stain small triglyceride droplets. However, it is not advantageous for staining larger droplets. | [Properties and Applications]
red. Red powder. Insoluble in water, soluble in ethanol, acetone and so on the many kinds of solvent, resistance to 5% of hydrochloric acid and sodium carbonate. In concentrated sulfuric acid to blue light green, dilution after red precipitation; 10% of the sulfuric acid insoluble; In concentrated hydrochloric acid of insoluble; In concentrated nitric acid for brown solution; In 10% sodium hydroxide solution insoluble. Used for fat, oil, wax and oil product color, also used in acrylic resin coloring. |
