Synthesis and Physicochemical Studies of Some Oxovanadium(IV) Complexes of Hydroxy- and Aminobenzoates

, 1990
The oxovanadium(IV) complexes of hydroxy- and amino-benzoates have been synthesized and characterised by micro-analysis, magnetic susceptibility measurements, infrared and electronic reflectance spectra. The complexes of the hydroxybenzoates appear to be

Zwitterion ratios of aminobenzoic acids

Australian Journal of Chemistry, 1969
Relations have been established between the pKa values for the non- zwitterionic forms of meta- and para-aminobenzoic acids, pKB, and the pKa values of the corresponding methyl and ethyl esters, pKE. For methyl m-aminobenzoate, the expression is pKB = pKE + 0.09, whilst for the ethyl ester it is pKB = pKE + 0.03.

PARA-AMINOBENZOIC ACID AND INDOLE METABOLISM

Archives of Dermatology, 1948
FOR THE past few years I have in private practice prescribed paraaminobenzoic acid in a variety of dermatoses, including hair and scalp conditions. A surprisingly common subjective response to this therapy has been a feeling of greater vigor, a loss of tired or enervated states. Some patients were so impressed with this result that they sought guidance
