Chemical Structure

3-Bromo-2,4-dimethyl-4H-furo[3,2-b]pyrrole-5-carboxylic acid CAS 1399654-68-2 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 258.07 g/mol gives 3-Bromo-2,4-dimethyl-4H-furo[3,2-b]pyrrole-5-carboxylic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

3-Bromo-2,4-dimethyl-4H-furo[3,2-b]pyrrole-5-carboxylic acid (CAS 1399654-68-2), molecular formula C9H8BrNO3 and molecular weight 258.07 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 3-Bromo-2,4-dimethyl-4H-furo[3,2-b]pyrrole-5-carboxylic acid (C9H8BrNO3) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
