5-Methyl-2-pyridone
The crystal structure of the title compound, C(6)H(7)NO, is stabilized by inter-molecular N-H⋯O hydrogen bonds, resulting in inversion dimers. The structure is further consolidated by weak C-H⋯O hydrogen bonds.
متن کاملThe excretion of N-methyl-2-pyridone-5-carboxamide by man following ingestion of several known or potential precursors.
The development of a rapid method for the determination of N-methyl2-pyridone-5-carboxamide (pyridone) in urine (1) has made it practical to attempt to confirm and extend the studies of Holman and de Lange (2) and others (3-5) concerning the excretion of the pyridone following the administration of various known or possible precursors to man. In the conversion of nicotinic acid to the pyridone ...
متن کاملChannel-forming solvate crystals and isostructural solvent-free powder of 5-hydroxy-6-methyl-2-pyridone.
Crystals of 5-hydroxy-6-methyl-2-pyridone, (I), grown from a variety of solvents, are invariably trigonal (space group R3); these are 5-hydroxy-6-methyl-2-pyridone acetone 0.1667-solvate, C(6)H(7)NO(2)·0.1667C(3)H(6)O, (Ia), and 6-methyl-5-hydroxy-2-pyridone propan-2-ol 0.1667-solvate, C(6)H(7)NO(2)·0.1667C(3)H(8)O, (Ib), and the forms from methanol, (Ic), water, (Id), benzonitrile, (Ie), and b...
متن کاملA fluorometric method for the determination of the 6-pyridone of N1-methylnicotinamide in urine.
Since Knox and Grossman demonstrated the excretion by man of the 6-pyridone of N’-methylnicotinamide (hereafter referred to as the pyridone) in appreciable amounts after the ingestion of nicotinamide (2), it became necessary to devise a method for its quantitative estimation in urine. Knox and Grossman isolated the compound from human urine and described its properties, including its ultraviole...
متن کاملSynthesis of 4-Pyridone-3-sulfate and an improved synthesis of 3-Hydroxy-4-Pyridone
An improved synthesis of 3-hydroxy-4-pyridone via an Elbs oxidation of 4-pyridone and isolation of 4-pyridone-3-sulfate is described.
