Applications:
Research and Analytical applications: Sudan Red 7B has been used in research laboratories for various purposes. It has been employed as a dye in staining techniques to visualize and study lipids in biological samples. It can selectively stain lipid-rich structures, allowing researchers to observe and analyze lipid content and distribution. Industrial applications: Sudan Red 7B has been employed in various industrial applications, including the coloring of plastics, waxes, and textiles. It can be used to provide a red hue to these materials, enhancing their visual appeal. However, similar to its use as a food colorant, its use in industrial applications is now restricted or limited due to safety concerns.

Sudan Red 7B (N-ethyl-1-[(4-phenyldiazenylphenyl)diazenyl]naphthalen-2-amine), also called “fat red” is a member of the Sudan family of hydrophobic lipid-staining dyes. Sudan dyes are a group of lipid soluble solvent dyes often called lysochromes, in structural classification they are diazo dyes. With the use of certain solvents, may also be used to stain some protein bound lipids in paraffin sections. Sudan Red 7B has also been used to stain suberin lamellae in plant tissues.
