The chemical formula of dichloropyrimidine is C4H2Cl2N2. It consists of four carbon atoms, two hydrogen atoms, two chlorine atoms, and two nitrogen atoms arranged in a six-membered heterocyclic ring.
Dichloropyrimidine is a pale to yellow crystalline compound, slightly soluble in water but soluble in organic solvents. It exhibits high chemical reactivity due to electron-deficient carbon atoms adjacent to the chlorine atoms.
The melting point of dichloropyrimidine varies by isomer, but it typically lies between 60°C and 90°C. Purity and positional isomerism may influence this thermal property.
Dichloropyrimidine generally has a boiling point in the range of 220°C to 240°C, depending on the specific isomer and atmospheric pressure. It should be heated with care in controlled conditions.
Dichloropyrimidine serves as an essential intermediate in pharmaceutical, agrochemical, and fine chemical industries. Its reactive chlorinated pyrimidine ring is ideal for nucleophilic substitution reactions in complex molecule formation.
