3-Hydroxyisonicotinaldehyde (HINA), also known as 3-hydroxypyridine-4-carboxaldehyde, is a derivative of pyridine, with hydroxyl and aldehyde substituents. It has been studied as a simple analogue of vitamin B 6. In 2020, it was reported as having the lowest molecular weight of all dyes which exhibit green fluorescence. [2] [3]
N-Methyl-3-piperidyl benzilate (JB-336, BZ) Piperidine is also commonly used in chemical degradation reactions, such as the sequencing of DNA in the cleavage of particular modified nucleotides . Piperidine is also commonly used as a base for the deprotection of Fmoc - amino acids used in solid-phase peptide synthesis .
The amide group can be involved in hydrogen bonding to other nitrogen- and oxygen-containing species.. The predominant solid state form is 2-pyridone. This has been confirmed by X-ray crystallography which shows that the hydrogen in solid state is closer to the nitrogen than to the oxygen (because of the low electron density at the hydrogen the exact positioning is difficult), and IR ...
Pyridine and poly(4-vinyl) pyridine have been shown to form conducting molecular wires with remarkable polyenimine structure on UV irradiation, a process which accounts for at least some of the visible light absorption by aged pyridine samples. These wires have been theoretically predicted to be both highly efficient electron donors and ...
Pyridine-3-carbaldehyde, also known as nicotinaldehyde, is an organic compound with the formula C 5 H 4 NCHO. It is one of three isomeric pyridinaldehydes. The other isomers are pyridine-2-carboxaldehyde and pyridine-4-carboxaldehyde. It is a colorless liquid that is routinely available commercially. It can be produced from nicotinonitrile ...
3-Hydroxy picolinic acid is a picolinic acid derivative and is a member of the pyridine family. It is used as a matrix for nucleotides in MALDI mass spectrometry analyses [ 1 ] and the synthesis of favipiravir .
Chloro(pyridine)cobaloxime(III) is first reduced to Chloro(pyridine)cobaloxime(I) by sodium borohydride in alkaline solution, then an alkyl halide is added into the reaction mixture, and the desired Co-C bond is formed via a S N 2 reaction. This method can be used to produce cobaloximes containing a primary or a secondary alkyl substituent.
