Acridine

Acridine is an organic compound and a nitrogen heterocycle. Acridine is structurally related to anthracene with one of the central CH groups is replaced by nitrogen. It is a raw material used for the production of dyes and some valuable drugs.Acridine occurs naturally in coal tar. It is separated from coal tar by extracting with dilute sulfuric acid.Acridine combines readily with alkyl iodides to form alkyl acridinium iodides, which are readily transformed by the action of alkaline potassium ferricyanide to N-alkyl acridones.Acridine is a known human carcinogen. It causes frameshift mutations in incorporating into the DNA, and doing so creating an additional base on the opposite strand.

Alizarin

Alizarin is an organic compound that is historically important as a prominent dye, originally derived from the roots of plants of the madder genus. It is the main ingredient for the manufacture of the madder lake pigments known to painters as Rose madder and Alizarin crimson. Alizarin red is used in a biochemical assay to determine, quantitatively by colorimetry, the presence of calcific deposition by cells of an osteogenic lineage. In clinical practice, it is also used to stain synovial fluid to assess for basic calcium phosphate crystals. In geology, it is used as a stain to indicate the calcium carbonate minerals, calcite and aragonite.

Amaranth

Amaranth is a dark red to purple azo dye used as a food dye and to color cosmetics. The name was taken from amaranth grain, a plant distinguished by its red color and edible protein-rich seeds. Amaranth is an anionic dye. It can be applied to natural and synthetic fibers, leather, paper, and phenol-formaldehyde resins. As a food additive it has E number E123. Amaranth usually comes as a trisodium salt. It has the appearance of reddish-brown, dark red to purple water-soluble powder that decomposes at 120 °C without melting. Amaranths water solution has absorption maximum at about 520 nm.

Biphenyl

Biphenyl is an aromatic hydrocarbon. It has a distinctively pleasant smell. It is notable as a starting material for the production of polychlorinated biphenyls, which were once widely used as dielectric fluids and heat transfer agents. Biphenyl is also an intermediate for the production of a host of other organic compounds such as emulsifiers, optical brighteners, crop protection products, and plastics.

Brazilin

Brazilin is a red pigment obtained from the wood of the brazilwood family. It has been used since at least the Middle Ages to dye fabric, and has been used to make paints and inks as well. It is closely related to the blue-black dye haematoxylin, having one less hydroxyl group. Brazilein is the name for the oxidised pigment.

Butanone

Butanone is an organic compound. It is an effective and common solvent and is used in processes involving gums, resins, cellulose acetate and nitrocellulose coatings and in vinyl films. For this reason it finds use in the manufacture of plastics, textiles, in the production of paraffin wax, and in household products such as lacquer, varnishes, paint remover, a denaturing agent for denatured alcohol, glues, and as a cleaning agent. It is also used in dry erase markers as the solvent of the erasable dye. As butanone melts polystyrene, it is sold as "polystyrene cement" for use in connecting together parts of scale model kits. Though often considered an adhesive, it is actually functioning as a welding agent in this context. It is the precursor to methyl ethyl ketone peroxide, a catalyst for some polymerization reactions.
