pyrimidine's Usage Examples:

It is considered to inhibit de novo pyrimidine synthesis in a manner similar to BQR (Figure 4).

It condenses with acetic anhydride to form a methyldiphenyl triazine, acetamide being also formed; with acetyl-acetone to form dimethylphenyl pyrimidine (A.

Its hydrochloride melts at 163° C., and crystallizes from alcohol in colourless deliquescent prisms. Acetic anhydride converts the base into an acetamino-dimethyl pyrimidine, acetic acid and acetamide being also formed.

The results at first obtained were very confusing and seemed to show that nucleic acid is very variable in constitution, but thanks to the work ~f Schmiedeberg and Stendel (Germany), Ivar Bang (Sweden) and Walter Jones and Levene (America), the confusion has been reduced to some sort of order, and it now seems probable that all ordinary nucleic acids yield two purine bases, adenine and guanine; two pyrimidine bases, cytosine and thymine and a hexose carbohydrate, the identity of which is uncertain.i The NucleolusIn the majority of plant-nuclei, both in the higher and lower plants, there is found, in addition to the chromatin network, a deeply stained spherical or slightly irregular body (sometimes more than one) called the nucleolus (fig.

For methods of preparation and properties of numerous other pyrimidine compounds see T.

Pyrimidine, C4H4N2, itself is a water-soluble base which melts at 21° C. and possesses a narcotic smell.

The purins themselves may be considered as a combination of the pyrimidine and glyoxaline ring systems. For formulae see below; the numbers about the first ring explain the orientation of pyrimidine derivatives.
