Chemical Structure

3,4,5-Tribromo-1H-pyrrole-2-carboxylic acid CAS 74039-30-8 chemical structure

Description

The occurrence of 3,4,5-Tribromo-1H-pyrrole-2-carboxylic acid is closely related to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 3,4,5-Tribromo-1H-pyrrole-2-carboxylic acid (CAS 74039-30-8), a certified reference material (molecular formula C5H2Br3NO2, MW 347.79 g/mol) for analytical method development and quality control.

3,4,5-Tribromo-1H-pyrrole-2-carboxylic acid (C5H2Br3NO2) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.

CATO manufactures 3,4,5-Tribromo-1H-pyrrole-2-carboxylic acid under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
