cf. C.A. 46, 9422c. The wave length of maximum absorption, λ, and the extinction coefficient of compounds of the type 5-nitro-2X-pyrimidine, in which X is Me, Ph, furyl, OH, OMe, SH, SMe, NH2, or Cl, were determined in 0.1 N HCl (pH 1), H2O (pH 7), and 0.1 N NaOH (pH 15), to discover if the NO2 group in position 5 would alter results previously found for mono-substituted compounds of the same type. In general the λ is fairly constant at pH 1-7, with the exception of X = CH3, when it jumps from 3065 to 3505 A. The compounds measured are classified as follows: symmetrical when X = NH2, quasisymmetrical when X = OH or SCH3, nonsymmetrical for the other 6 derivatives measured.
