hydrocarbons

Ponceau 4R (Acid Red 18) is a synthetic strawberry red azo dye that is a food colorant dye used in a variety of food products. It is stable to light, heat and acid, but fades in the presence of ascorbic acid. It is usually synthesized from aromatic hydrocarbons.

Pyrene is a carcinogenic polycyclic aromatic hydrocarbon (PAH) and a sensitive blue fluorescent group with an excitation wavelength of 338 nm and an emission wavelength of 375 nm. It can be used to detect protein-lipid interactions and conformational changes and also serves as an electron donor material.
