Chitin

Chitin is a long-chain polymer of a N-acetylglucosamine, a derivative of glucose, and is found in many places throughout the natural world. It is the main component of the cell walls of fungi, the exoskeletons of arthropods such as crustaceans and insects, the radulas of mollusks and the beaks of cephalopods, including squid and octopuses. Chitin may be compared structurally to the polysaccharide cellulose and functionally to the protein keratin. Chitin has also proven useful for several medical and industrial purposes. It is used as an additive to thicken and stabilize foods and pharmaceuticals. It also acts as a binder in dyes, fabrics, and adhesives. Industrial separation membranes and ion-exchange resins can be made from chitin.

Cobalt

Cobalt is found naturally only in chemically combined form. It is used in the preparation of magnetic, wear-resistant and high-strength alloys. Cobalt silicate and cobalt(II) aluminate give a distinctive deep blue color to glass, smalt, ceramics, inks, paints and varnishes. Lithium cobalt oxide is widely used in lithium ion battery cathodes. Several cobalt compounds are used in chemical reactions as oxidation catalysts. Other uses of cobalt are in electroplating, owing to its attractive appearance, hardness and resistance to oxidation, and as ground coats for porcelain enamels.

Indigo

Indigo is an organic compound with a distinctive blue color. It is the blue often associated with blue jeans.Indigo is among the oldest dyes to be used for textile dyeing and printing. Many Asian countries, such as India, China, Japan, and Southeast Asian nations have used indigo as a dye.It is insoluble in water, alcohol, or ether, but soluble in DMSO, chloroform, nitrobenzene, and concentrated sulfuric acid.Indigo and some of its derivatives are known to be ambipolar organic semiconductors when deposited as thin films by vacuum evaporation.

Orcein

Orcein are names for dyes extracted from several species of lichen. Orcinol is extracted from such lichens. It is then converted to orcein by ammonia and air. In traditional dye-making methods, urine was used as the ammonia source.It is red in acidic pH and blue in alkaline pH. It forms dark brown crystals. It is a mixture of phenoxazone derivates - hydroxyorceins, aminoorceins, and aminoorceinimines.

Aniline

Aniline is an organic compound. Aniline was first isolated by destructive distillation of indigo by Otto Unverdorben. Aniline is the prototypical aromatic amine. Its main use is in the manufacture of precursors to polyurethane. Aniline is mainly produced in industry in two steps from benzene. First, benzene is nitrated using a concentrated mixture of nitric acid and sulfuric acid at 50 to 60 °C, which gives nitrobenzene. In the second step, the nitrobenzene is hydrogenated, typically at 200–300 °C in presence of various metal catalysts. Aniline reacts with carboxylic acids or more readily with acyl chlorides such as acetyl chloride to give amides. Aniline and its ring-substituted derivatives react with nitrous acid to form diazonium salts. It reacts with nitrobenzene to produce phenazine in the Wohl-Aue reaction.
