Description

Compared with other compounds in its class, the molecular weight of 208.64 g/mol gives 5-chloro-2-ethyl-1H-pyrrolo[2,3-b]pyridine-3-carbaldehyde distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

5-chloro-2-ethyl-1H-pyrrolo[2,3-b]pyridine-3-carbaldehyde (CAS 954112-64-2), molecular formula C10H9ClN2O and molecular weight 208.64 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 5-chloro-2-ethyl-1H-pyrrolo[2,3-b]pyridine-3-carbaldehyde (C10H9ClN2O) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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), 5-chloro-2-ethyl-1H-pyrrolo[2,3-b]pyridine-3-carbaldehyde 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.
