Detection of Purine Metabolite Uric Acid with Picolinic Acid Functionalized Metal Organic Framework.
ACS Applied Materials and Interfaces, 2019Uric acid (UA) is a purine metabolite closely related to the metabolic function of human. Fluorescence analysis is a very effective method because of high selectivity and sensitivity but still remains a great challenge for direct UA detection.

Mechanism of copper electrodeposition in the presence of picolinic acid
Electrochimica Acta, 2006Abstract The influence of picolinic acid (PA) on copper deposition from a slightly acidic sodium sulphate electrolyte has been studied over a wide range of concentration and pH by cyclic voltammetry. The mechanism by which the copper electrodeposition process in the presence of PA takes place, depends on the chemistry and electrochemistry ...

6-Phosphoryl Picolinic Acids as Europium and Terbium Sensitizers
Inorganic Chemistry, 2011Three 6-phosphoryl picolinic acid (6PPA) derivatives were synthesized and used as europium and terbium sensitizers. Two of the three ligands (6-diethoxyphosphoryl picolinic acid (Hdeppa) and 6-monoethoxyphosphoryl picolinic acid (H(2)meppa)) are water-soluble, once complexed to lanthanide ions, while the third (6-dihydroxyphosphoryl picolinic acid (H(3)

α-Picolinic acid as a colorimetric reagent
Analytica Chimica Acta, 1953Abstract Aluminium, can easily be separated from solutions containing iron or chromium at an optimum pH of 5.8 to 6.85 for iron and at 6.25 to 7.05 for chromium, in the presence of an excess of α-picolinic acid, which acts as a masking agent for both.

Role of zinc in blockade of excitotoxic action of quinolinic acid by picolinic acid
Amino Acids, 1998This study examined whether picolinic acid (PIC) inhibits quinolinic acid (QUIN)-induced excitotoxicity through zinc chelation. Injection of QUIN into the nucleus basalis magnocellularis significantly depleted cortical choline acetyltransferase activity 7 days post injection and PIC inhibited this response. Zinc augmented the QUIN- but not NMDA-induced
