4-Bromo-2-chloro-1H-pyrrolo[2,3-b]pyridine CAS 2779693-79-5

Description

The occurrence of 4-Bromo-2-chloro-1H-pyrrolo[2,3-b]pyridine is closely related to a nitrile group, chlorine/bromine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

4-Bromo-2-chloro-1H-pyrrolo[2,3-b]pyridine (CAS 2779693-79-5) is a high-purity analytical reference standard with the molecular formula C7H4BrClN2 and a molecular weight of 231.48 g/mol.

Owing to a nitrile group, chlorine/bromine substitution, an aromatic ring system, 4-Bromo-2-chloro-1H-pyrrolo[2,3-b]pyridine is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 231.48 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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), 4-Bromo-2-chloro-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.
