Chemical Structure
Description
The occurrence of 5-Bromo-4-chloro-7-tosyl-7H-pyrrolo[2,3-d]pyrimidine is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine/bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 5-Bromo-4-chloro-7-tosyl-7H-pyrrolo[2,3-d]pyrimidine (CAS 1143534-78-4), a certified reference material (molecular formula C13H9BrClN3O2S, MW 386.65 g/mol) for analytical method development and quality control.
The molecular framework of 5-Bromo-4-chloro-7-tosyl-7H-pyrrolo[2,3-d]pyrimidine (C13H9BrClN3O2S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine/bromine 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
