Crystal structure of 4-carbamoylpyridinium chloride

چکیده
The hydro-chloride salt of isonicotinamide, C6H7N2O(+)·Cl(-), has been synthesized from a dilute solution of hydro-chloric acid in aceto-nitrile. The compound displays monoclinic symmetry (space group C2/c) at 150 K, similar to the related hydro-chloride salt of nicotinamide. The asymmetric unit contains one protonated isonicotinamide mol-ecule and a chloride anion. An array of hydrogen-bonding inter-actions, including a peculiar bifurcated pyridinium-chloride inter-action, results in linear chains running almost perpendicularly in the [150] and [1-50] directions within the structure. A description of the hydrogen-bonding network and comparison with similar compounds are presented.

A fluorometric method for the determination of phenylpyruvic acid (PPA) has been established. Benzaldehyde formed from PPA by alkaline decomposition is quantified by means of its fluorogenic reaction with 1,4-dimethyl-3-carbamoylpyridinium chloride. PPA can be determined in the range of 0.1-3 nmol/50 ƒÊl with the relative standard deviation of 4.0-4.1%. About 70% recovery was obtained when a ur...
