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.

In medicine, a clinical study report (CSR) on a clinical trial is a document, typically very long, providing much detail about the methods and results of a trial. A CSR is a scientific document addressing efficacy and safety, not a sales or marketing tool; its content is similar to that of a peer-reviewed academic paper. [ 1 ]
A case report form (or CRF) is a paper or electronic questionnaire specifically used in clinical trial research. [1] The case report form is the tool used by the sponsor of the clinical trial to collect data from each participating patient.
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.
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.
Thiolactones can be prepared by dehydration of thiol-containing carboxylic acids. Thiolactones can be hydrolyzed back to the thiol acids under basic conditions. [ 1 ] β-Thiolactones can be opened by reaction at the 4-position via S N 2 nucleophilic reactions .
