2-Nitro-p-phenylenediamine is a low molecular weight red dye which is able to penetrate into hair shafts; this compound is one of the most commonly used dyes in semi-permanent hair colorants. 2-Nitro-p-phenylenediamine is also an ingredient in permanent hair dye formulations.

Osajin is the major bioactive isoflavone present in the fruit of Maclura pomifera, commonly referred to as the Osage orange. Osajin have potent cardioprotective effects in perfused rat hearts and kidney subjected to global ischemia and reperfusion. Its effects may be mediated through the inhibition of lipid peroxidation. Osajin can antagonize myocardial injury induced by I/R through inhibiting oxidative stress. Osajin had a noticeable inhibition of AChE with IC(50) values of 2.239 mM.

Ergosterol endoperoxide is a derivative of ergosterol. It has been isolated from a variety of fungi, yeast, lichens and sponges. Ergosterol endoperoxide has been shown to inhibit the growth of some cancer cells and to induce apoptosis of HL60 human leukemia cells. Ergosterol endoperoxide also decreases lipid peroxidation of rat liver microsomes and suppresses the proliferation of mouse and human lymphocytes stimulated with mitogens. It has been reported as having immunosuppressive, antiplasmodial, antimycobacterial, antiviral, anti-inflammatory and antitumoural properties. The interaction of Trypanosoma cruzi with ergosterol peroxide in vitro resulted in a strong lytic activity possibly due to the disruption of the parasite membrane.

Phenyl benzoate is a white powdery organic compound that falls into the broad category of chemicals known as esters. The compound is formed in a reaction between phenol, sodium hydroxide and benzonyl chloride. The compound is solid at room temperature, but can form an oily liquid at a relatively low temperature. Phenyl benzoate can be used in a variety of polyesters, which have applications in products from clothing to heavy industry. One use that takes advantage of the electrical properties of phenyl benzoate is the development of liquid crystal displays. Phenyl benzoate based liquid crystals have excellent compatibility characteristics with other materials used in liquid crystal displays, such as biphenyl, phenylcyclohexane, bicyclohexane and fluorine types, especially at low temperatures. Phenyl benzoate is considered an excellent starting material for the production of optical components, particularly high quality lenses for still and motion picture cameras.
