Industrially it is produced from phthalic anhydride, beginning with amination: A recent food safety concern has arisen from the unapproved use of certain phthalates in a broad range of food/nutraceutical ingredients from Taiwan [53]. Structure-activity relationships with the parent structure provided information that could direct further investigation on structure modificatio … It is also incompatible with oxidizers. Phthalic acid esters have been used as plasticizers in numerous products and classified as endocrine-disrupting compounds. A structure analysis of sodium acid phthalate hemihydrate was undertaken as part of an investigation of a series of salts of phthalic acid.1 The aim of the investigation was an attempt to correlate the structural features and anomalous properties observed in these compounds by Mattson and Ehlert.2 A Users can perform simple and advanced searches based on annotations relating to sequence, structure and function. o-Phthalic acid molecules act as bridge between two Cu(II), one carboxylate binds to one Cu(II) as bidentate while the other carboxylate binds to another Cu(II) as monodentate. Singh N(1), Dalal V(1), Kumar P(2). U.S. Pat. … Phthalic acid is an organic compound derived from benzene and used in the manufacture of dyes, perfumes, pharmaceuticals, and synthetic fibers. The IUPAC name given to phthalic acid is Benzene-1,2-dicarboxylic acid. Chronic toxicity and carcinogenicity studies of several phthalic acid esters (PAEs) and compounds containing a 2-ethylhexyl moiety were conducted in Fischer 344 rats and B6C3F1 (hybrid) mice.
