Brassidic acid (22 carbon atoms) was first prepared from erucic acid by Reimer W. in 1886. It is a monounsaturated (one trans (E) double bond; shorthand nomenclature cannot be used to name trans fatty acids) fatty acid member of the sub-group called very long chain fatty acids (VLCFA), from 20 carbon atoms onwards, and is the trans-isomer of erucic acid. At a concentration of 0.1 mM, brassidic acid produced small increases in palmitoyl-CoA oxidation and carnitine acetyltransferase activities in hepatocytes cultured 70 hr.

Poppy acid occurs in opium (Papaver somniferum) and other Papaver species. Meconic acid has been described as a mild narcotic, but it has little or no physiological action, and is not now used medicinally. Its chemical reactions are of importance in toxicology as a valuable indication of the presence of opium.

Molybdenum trioxide (MoO3) is used primarily as an additive to steel and corrosion-resistant alloys. It is also used as a chemical intermediate for molybdenum products; an industrial catalyst; a pigment; a crop nutrient; components of glass, ceramics, and enamels; a flame retardant for polyester and polyvinyl chloride resins; and a reagent in chemical analyses. Molybdenum trioxide was nominated by the NCI for toxicity and carcinogenicity studies as a representative inorganic molybdenum compound. In addition some studies were done, showing the potential utility of MoO3 for treating metastatic cancer cells, which might enable advancements in cancer therapy.

Sodium fluoroborate (sodium tetrafluoroborate) is an inorganic compound with the formula NaBF4. It is used in the sand casting of aluminum, electrochemical processes, and as fluorinating agent. It is also used as an additive in chrome, nickel and cadmium plating baths. Sodium tetrafluoroborate may be used as a catalyst for the synthesis of bis(indolyl)methanes via electrophilic substitution reaction of indoles with aldehydes and ketones. It may also be used as a source of tetrafluoroborate anoins during the synthesis of ionic liquids like 1-butyl-3-methylimidazolium tetrafluoroborate[4] and trihexyl(tetradecyl)phosphonium tetrafluoroborate.
