7-Bromo-5H-pyrrolo[2,3-b]pyrazine-2-carboxylic acid CAS 2168444-66-2

Description

The occurrence of 7-Bromo-5H-pyrrolo[2,3-b]pyrazine-2-carboxylic acid is closely related to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

7-Bromo-5H-pyrrolo[2,3-b]pyrazine-2-carboxylic acid (CAS 2168444-66-2) is a high-purity analytical reference standard with the molecular formula C7H4BrN3O2 and a molecular weight of 242.03 g/mol.

7-Bromo-5H-pyrrolo[2,3-b]pyrazine-2-carboxylic acid (C7H4BrN3O2) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system. It is notably hygroscopic, 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. 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.
