Chemical Structure

Ethyl 4-bromo-2-{1H-pyrrolo[2,3-b]pyridin-5-yloxy}benzoate CAS 1630101-74-4 chemical structure

Description

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.

Ethyl 4-bromo-2-{1H-pyrrolo[2,3-b]pyridin-5-yloxy}benzoate (CAS 1630101-74-4), molecular formula C16H13BrN2O3 and molecular weight 361.19 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution, Ethyl 4-bromo-2-{1H-pyrrolo[2,3-b]pyridin-5-yloxy}benzoate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 361.19 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
