Chemical Structure
Description
6-Bromo-3-(difluoromethyl)-1H-pyrrolo[2,3-b]pyridine (CAS 2090237-47-9) is a high-purity analytical reference standard with the molecular formula C8H5BrF2N2 and a molecular weight of 247.04 g/mol.
6-Bromo-3-(difluoromethyl)-1H-pyrrolo[2,3-b]pyridine (C8H5BrF2N2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine/bromine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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-3-(difluoromethyl)-1H-pyrrolo[2,3-b]pyridine 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.
