Chemical Structure

5-methoxy-1H-pyrrolo[2,3-b]pyridine-3-carbaldehyde CAS 183208-38-0 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5-methoxy-1H-pyrrolo[2,3-b]pyridine-3-carbaldehyde.

5-methoxy-1H-pyrrolo[2,3-b]pyridine-3-carbaldehyde (CAS 183208-38-0), molecular formula C9H16N2O2 and molecular weight 184.24 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, 5-methoxy-1H-pyrrolo[2,3-b]pyridine-3-carbaldehyde is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 184.24 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
