Chemical Structure

5-Methoxy-4-methyl-1H-pyrrolo[2,3-b]pyridine-3-carboxylic acid CAS 1190322-79-2 chemical structure

Description

As a certified reference material (CRM), 5-Methoxy-4-methyl-1H-pyrrolo[2,3-b]pyridine-3-carboxylic acid 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.

5-Methoxy-4-methyl-1H-pyrrolo[2,3-b]pyridine-3-carboxylic acid (CAS 1190322-79-2), molecular formula C10H10N2O3 and molecular weight 206.20 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-4-methyl-1H-pyrrolo[2,3-b]pyridine-3-carboxylic acid is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 206.20 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.
