7-(2,4-Dichlorophenyl)-2-methylpyrazolo[1,5-a]pyrimidine CAS 478258-92-3

Description

The occurrence of 7-(2,4-Dichlorophenyl)-2-methylpyrazolo[1,5-a]pyrimidine is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

7-(2,4-Dichlorophenyl)-2-methylpyrazolo[1,5-a]pyrimidine (CAS 478258-92-3) is a high-purity analytical reference standard with the molecular formula C13H9Cl2N3 and a molecular weight of 278.14 g/mol.

Based on its molecular formula C13H9Cl2N3, 7-(2,4-Dichlorophenyl)-2-methylpyrazolo[1,5-a]pyrimidine contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 278.14 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
