Chemical Structure
Description
The occurrence of 6-Bromo-7H-pyrrolo[2,3-d]pyrimidine is closely related to a nitrile group, bromine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 6-Bromo-7H-pyrrolo[2,3-d]pyrimidine (CAS 89280-82-0), a certified reference material (molecular formula C6H4BrN3, MW 198.02 g/mol) for analytical method development and quality control.
Owing to a nitrile group, bromine substitution, an aromatic ring system, 6-Bromo-7H-pyrrolo[2,3-d]pyrimidine is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 198.02 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
As a certified reference material (CRM), 6-Bromo-7H-pyrrolo[2,3-d]pyrimidine meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
