Interaction of 3-Hydroxybenzoate with 3-Hydroxybenzoate-6-hydroxylase

Biotechnology Progress, 2001
The gradual quenching of the emission fluorescence of 3-HBA in the visible region upon titration with 3-HBA-6-hydroxylase and distinct changes in the near-UV circular dichroic spectrum of the enzyme in the presence of substrate suggest the formation of a stable enzyme-substrate complex.

Dimethacrylates Derived from Hydroxybenzoic Acids

Journal of Dental Research, 1976
Aromatic ether-ester dimethacrylates were synthesized directly from the three isomeric hydroxybenzoic acids and 2-bromoethyl methacrylate by facale condensation reactions. The three crystalline monomers, on proper admixture, form a liquid ternary eutectic.

Excited-state proton transfer of 3-hydroxybenzoic acid and 4-hydroxybenzoic acid

Spectrochimica Acta Part A: Molecular and Biomolecular Spectroscopy, 2010
The excited-state proton transfer of 3-hydroxybenzoic acid and 4-hydroxybenzoic acid was studied by time-resolved laser-induced fluorescence spectroscopy with ultra-short laser pulses. The excited-state reactions were identified in aqueous media as a function of the pH value.

10-Hydroxybenzo[h]quinoline

Acta Crystallographica Section C Crystal Structure Communications, 1995
The crystal structure of 10-hydroxybenzo[h]quinoline, C 13 H 9 NO, has been determined. The asymmetric part of the unit cell comprises two almost planar molecules. A strong intramolecular O-H...N hydrogen bond closes the six-membered ring. The geometrical features of the molecule suggest that it can be regarded as a 2-phenylpyridine with a fused double

TEAC antioxidant activity of 4-hydroxybenzoates

Free Radical Biology and Medicine, 1999
The influence of pH, intrinsic electron donating capacity, and intrinsic hydrogen atom donating capacity on the antioxidant potential of series of hydroxy and fluorine substituted 4-hydroxybenzoates was investigated experimentally and also on the basis of computer calculations.

Polyesters of hydroxybenzoic acids

Journal of Applied Polymer Science, 1959
Polymers and copolymers were prepared from the acetoxy derivatives of m- and p-hydroxybenzoic acids. Molecular weights of over 20,000 were obtained for poly(m-hydroxybenzoic acid) and copolymers containing up to 60% para isomer. These polyesters were crystalline, and the degree of crystallinity increased as the para isomer content was increased. Blocks

2,3-Diaminopyridinium 4-hydroxybenzoate

2009
In the title compound, C5H8N3+·C7H5O3−, the pyridine N atom is protonated. In the 4-hydroxy­benzoate anion, the carboxyl­ate group is twisted slightly out of the benzene ring plane by an angle of 3.77 (5)°. The protonated N atom and one of the two amino groups are hydrogen-bonded to the 4-hydroxy­benzoate anion through a pair of N—H⋯O hydrogen bonds ...
