Reductions of picolinic acid and dipicolinic acid at mercury cathodes
Journal of Electroanalytical Chemistry and Interfacial Electrochemistry, 1975Summary Picolinic acid and dipicolinic acid have been successfully reduced to the corresponding alcohols by controlled potential electrolysis at mercury cathodes in slightly acidic aqueous buffer solutions.

Picolinic Acid in Acrodermatitis Enteropathica
Journal of Pediatric Gastroenterology and Nutrition, 1984SummaryThree children with acrodermatitis enteropathica (AE) were treated with oral zinc dipicolinate (zinc‐PA). The daily dose of zinc required to prevent exacerbations, when administered as the dipicolinate complex, was one‐third the minimum amount of zinc required as the sulfate salt. The concentration of picolinic acid in the plasma of asymptomatic

New Derivatives of Picolinic Acid and Nicotinic Acid with Anticonvulsant Activity
Protein & Peptide Letters, 2005Previously obtained Pic-BZA is a potent anticonvulsant with low neurotoxicity, but its half-time of action is only about 15 min. In search for equally effective anticonvulsants but with a longer time of action fourteen Pic-BZA analogs were obtained.

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.
