摘要：
A novel bipyrimidinyl derivative which is superior in practical properties and useful as a high temperature liquid crystal component constituting a physically and chemically stable liquid crystal composition is provided, which bipyrimidinyl derivative is a 2,5'-disubstituted-5,2'-bipyrimidinyl expressed by the formula ##STR1## wherein ##STR2## X represents a halogen atom of F, Cl or Br or cyano group or an alkyl group or an alkoxy group each having 1 to 10 carbon atoms and R represents an alkyl group or an alkoxy group each having 1 to 10 carbon atoms.
