Abstract
Abstract Novel compounds capable of improving various characteristics required for liquid crystal compositions when added to liquid crystal substances, and liquid crystal compositions containing the same are provided, which novel compounds are halogenopyrimidine derivatives expressed by the general formulawherein R<sup>1</sup> represents an alkyl group of 1 to 10 carbon atoms, R<sup>2</sup> represents a halogen atom of F, Cl or Br and represents 1 or 2.
