Most commonly called quinoline, this compound is naturally found in coal tar. It was first extracted in 1834 by German chemist F. Runge and is now used as a flavoring agent, preservative, disinfectant and solvent. It can also be used to make fungicides, dyes, rubber chemicals, and drugs (especially anti-malarial medicines). It is one of several compounds that add to the bitterness in coffee. Although it is safe in our food, it is highly toxic in its vapor form. If inhaled, acute exposure can irritate respiratory tract and cause headaches, nausea, or a coma.

Apatite can be any of three different minerals depending on the predominance of fluorine, chlorine, or the hydroxyl group. It is typically green, and either transparent or translucent. It is prominently found and produced in Mexico, Ontario, Germany, Russia, USA, Sri Lanka and Brazil. Apatite can be cut into gemstones, although it is too soft and brittle to be highly durable. Its main use is as a source of phosphate for fertilizer. An interesting fact about the name "apatite" is that it is part of what makes up the teeth in all vertebrate animals.

Azurite is a monoclinic blue crystal whose name is derived from the Arabic word, azure meaning blue. During the fifteenth and seventeenth centuries azurite was used as a blue paint pigment, but this pigment changes to green over time. This occurs because azurite reacts with water to produce malachite, which is green. Today this mineral is still used as a pigment, and as a minor ore of copper, an ornamental stone, and in jewelry. Azurite is found in many places but has notable occurrences in Utah, Arizona, New Mexico, and Morocco.

BHA is a phenolic mixture of isomers used as a food additive in butter, meats, chewing gum, potatoes, beer, and also in other manufactured goods such as cosmetics, rubber, and petroleum based products as well as others. As an antioxidant, BHA reacts preferentially with oxygen rather than allowing the oxidation of the fats and oils already present, thereby protecting the product from breaking down and spoiling. This fat-soluble preservative has a white to yellowish color as a waxy solid with a faint aromatic odor. Some studies have shown that there are individuals that experience difficulty in metabolizing BHA which can cause changes in behavior and health. Medically this compound has shown some antiviral and antimicrobial activity and may be of use in the treatment of herpes simplex and AIDS.

This pheromone was identified and synthesized by the Roelof group in the Department of Entomology, Cornell University, in 2005. It is produced in the sex-pheromone producing glands of the female German cockroach (blattela germanica). In the future it might find application in trapping cockroaches as they are worldwide the most common residential and food-associated pests.

This is a powerful aromatic compound commonly called “caramel furanone” because it smells like maple syrup and Fenugreek. It is hypothesized that Sotolon is formed from α-ketobutyric acid and acetaldehyde. It is responsible for the sweet, caramel flavor in coffee and is a main contributor to white wine rancidity. It can be found in liquid whey, sugar, some tobacco, and a variety of wines. Sotolon’s spicy aroma is highly potent and has an odor detection threshold of 0.001 ppb.

Corundum or ruby is one of the oldest gems known to man. There is evidence of a Greek scholar, Theophastus, classifying precious stones such as rubies as early as 350 B.C. The first time Rubies were introduced in Europe was during the Greco-Roman times. Some of the best known producers of Corundum around the world are Southeast Asia, Australia, and southern Africa. In the U.S., it is found in North Carolina and Montana. Corundum is basically used as a gemstone for jewelry, but because of the high price scientists have made an inexpensive synthetic ruby. It is also used as an abrasive because of its hardness; it is employed industrially as a component of large machines to sandpaper.

Ethyl acetate is a colorless, volatile liquid with a mild and fragrant odor. It is used as solvent in chemistry laboratories but can also be found in many household products such as paints, coatings, and adhesives. The compound is also used in some extraction processes such as decaffeination or purification of antibiotics. It is present in both nail polish and removers. Some synthetic fruit essences may contain this and other esters. Etymologists like to use this solvent for insect collecting as the vapor kill the insect quickly and keep it soft for mounting.
