Description

Description

Applications
Chlorouracil (4-Chlorouracil; 6-Chlorouracil) is a halogenated uracil that is useful in studies of the effects of halogenation on nucleic acid base-pair stability and alkali metal ion affinity. Reaction of 6-chlorouracil with 4-(dimethylamino)pyridine, 4-methylpyridine, and pyridin-4-yl-morpholine yielded pyridinium-substituted uracils as chlorides which were converted into pyridinium uracilates by deprotonation. These heterocyclic mesomeric betaines are cross-conjugated and thus possess separate cationic (pyridinium) and anionic (uracilate) moieties. Calculations and X-ray single crystal analyses may be used to characterize these systems and to compare the salts with the betaines.

Solubility
Soluble in Ammonium Hydroxide

Notes
Store away from strong oxidizing agents. Keep container tightly closed. Store in cool, dry conditions in well sealed containers.
