4-Chloro-5-(4-fluorophenyl)-7-(4-methoxyphenyl)-7H-pyrrolo[2,3-d]pyrimidine (CAS 907585-55-1), molecular formula C19H13ClFN3O and molecular weight 353.78 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 4-Chloro-5-(4-fluorophenyl)-7-(4-methoxyphenyl)-7H-pyrrolo[2,3-d]pyrimidine (C19H13ClFN3O) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
