4-Chloro-7-(4-methoxy-phenyl)-5-phenyl-7H-pyrrolo[2,3-d]pyrimidine CAS 220835-25-6

Description

The occurrence of 4-Chloro-7-(4-methoxy-phenyl)-5-phenyl-7H-pyrrolo[2,3-d]pyrimidine is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

4-Chloro-7-(4-methoxy-phenyl)-5-phenyl-7H-pyrrolo[2,3-d]pyrimidine (CAS 220835-25-6) is a high-purity analytical reference standard with the molecular formula C19H14ClN3O and a molecular weight of 335.79 g/mol.

Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, 4-Chloro-7-(4-methoxy-phenyl)-5-phenyl-7H-pyrrolo[2,3-d]pyrimidine is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 335.79 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
