4-Chloro-5-(difluoromethyl)-7H-pyrrolo[2,3-d]pyrimidine (CAS 2090261-97-3), molecular formula C7H4ClF2N3 and molecular weight 203.58 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 4-Chloro-5-(difluoromethyl)-7H-pyrrolo[2,3-d]pyrimidine (C7H4ClF2N3) is characterized by a nitrile group, fluorine/chlorine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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).
