2-Bromopyridine reacts with butyllithium to give 2-lithiopyridine, [2] which is a versatile reagent. [3] Pyrithione can be prepared in a two-step synthesis from 2-bromopyridine by oxidation to the N-oxide with a suitable peracid followed by substitution using either sodium dithionite or sodium sulfide with sodium hydroxide to introduce the thiol functional group.
Pyrithione is the common name of an organosulfur compound with molecular formula C 5 H 5 NOS, chosen as an abbreviation of pyridinethione, and found in the Persian shallot. [4] It exists as a pair of tautomers, the major form being the thione 1-hydroxy-2(1H)-pyridinethione and the minor form being the thiol 2-mercaptopyridine N-oxide; it crystallises in the thione form.

2-Mercaptopyridine and the disulfide are chelating ligands. 2-mercaptopyridine forms the indium(III) complex In(PyS)3 complexes in supercritical carbon dioxide. [7] 2-Mercaptopyridine may also be used to coat porous media in order to purify plasmid DNA of impurities such as RNA and proteins at relatively quick timescales to similar methods.
N1-Methyl-2-pyridone-5-carboxamide (also known as 1-methyl-6-oxopyridine-3-carboxamide or nudifloramide and abbreviated as 2PY, 2-Py or NMPC) is one of a number of metabolic products of nicotinamide adenine dinucleotide (NAD) degradation.
Shares of Lilly rose 4.4% to $962.02 in early trading, adding to an over 60% rise in stock value this year. In a trial involving 1,032 adults, patients who were on weekly injections showed a 94% ...
This reaction is rapid and stoichiometric, with the addition of one mole of thiol releasing one mole of TNB. The TNB 2− is quantified in a spectrophotometer by measuring the absorbance of visible light at 412 nm, using an extinction coefficient of 14,150 M −1 cm −1 for dilute buffer solutions, [4] [5] and a coefficient of 13,700 M −1 cm −1 for high salt concentrations, such as 6 M ...
