The occurrence of 6-(4-Aminophenyl)-N-(3-chlorophenyl)-7H-pyrrolo[2,3-d]pyrimidin-4-amine 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.
6-(4-Aminophenyl)-N-(3-chlorophenyl)-7H-pyrrolo[2,3-d]pyrimidin-4-amine (CAS 187723-38-2), molecular formula C18H14ClN5 and molecular weight 335.79 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 6-(4-Aminophenyl)-N-(3-chlorophenyl)-7H-pyrrolo[2,3-d]pyrimidin-4-amine (C18H14ClN5) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
