Glycine–phthalic acid (1/1)
In the title compound, C2H5NO2·C8H6O4, the glycine mol-ecule exists as a zwitterion (2-aza-niumyl-ethano-ate) with a positively charged amino group and a negatively charged carboxyl-ate group. In the crystal, N-H⋯O and O-H⋯O hydrogen bonds link the components into layers parallel to the ab plane. The central part of each layer is composed of hydrogen-bonded glycine zwitterions, while phthalic a...
متن کاملBacterial Decarboxylation of o-Phthalic Acids.
The decarboxylation of phthalic acids was studied with Bacillus sp. strain FO, a marine mixed culture ON-7, and Pseudomonas testosteroni. The mixed culture ON-7, when grown anaerobically on phthalate but incubated aerobically with chloramphenicol, quantitatively converted phthalic acid to benzoic acid. Substituted phthalic acids were also decarboxylated: 4,5-dihydroxyphthalic acid to protocatec...
متن کاملToxicological Characterization of Phthalic Acid
There has been growing concern about the toxicity of phthalate esters. Phthalate esters are being used widely for the production of perfume, nail varnish, hairsprays and other personal/cosmetic uses. Recently, exposure to phthalates has been assessed by analyzing urine for their metabolites. The parent phthalate is rapidly metabolized to its monoester (the active metabolite) and also glucuronid...
متن کاملPhthalic acid esters--an overview.
In recent years those in the scientific community concerned with environmental and public health have been called upon to consider two categories of previously unsuspected materials characterized by wide distribution and long persistence in the environment: mercury, especially organic mercury, and the chlorinated diphenyls (PCBs). To a significant extent this conference presents again the same ...
متن کامل4,6-Dichloro-5-methoxypyrimidine
The mol-ecule of the title compound, C(5)H(4)Cl(2)N(2)O, is close to being planar (r.m.s. deviation = 0.013 Å), apart from the C atom of the meth-oxy group, which deviates by 1.082 (2) Å from the mean plane of the other atoms. In the crystal, short Cl⋯N contacts [3.0940 (15) and 3.1006 (17) Å] generate a three-dimensional framework.
