Aspergillic acid acetic acid gives a diketopiperazine. Hydrolysis with HBr yields a mixture of -leucine and -isoleucine. These reaction schemes can be seen below: Aspergillic acid Aspergillic acid is an organic chemical compound with the molecular formula CHNO. It has a pale yellow crystalline appearance. Aspergillic acid is most commonly known as an antibiotic and antifungal agent that is derived from certain strains of the fungus "Aspergillus flavus". In 1940 Edwin C. White and Justina H. Hill discovered that a fungal strain of "Aspergillus flavus" growing in a surface culture on a tryptone-salt was capable of producing a bactericidal filtrate. It has
2-Ethylhexanoic acid and industrial chemical synthesis. They function as catalysts in polymerizations as well as for oxidation reactions as "oil drying agents." They are highly soluble in nonpolar solvents. These metal complexes are often described as salts. They are, however, not ionic but charge-neutral coordination complexes. Their structures are akin to the corresponding acetates. 2-Ethylhexanoic acid 2-Ethylhexanoic acid is the organic compound with the formula CH(CH)CH(CH)COH. It is a carboxylic acid that is widely used to prepare lipophilic metal derivatives that are soluble in nonpolar organic solvents. 2-Ethylhexanoic acid is a colorless viscous oil. It is supplied as a racemic mixture. 2-Ethylhexanoic
