2-(3,5-Dibromo-2-oxopyridin-1(2H)-yl)acetic acid CAS 871875-90-0 chemical structure

Description

The occurrence of 2-(3,5-Dibromo-2-oxopyridin-1(2H)-yl)acetic 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.

2-(3,5-Dibromo-2-oxopyridin-1(2H)-yl)acetic acid (CAS 871875-90-0), molecular formula C7H5Br2NO3 and molecular weight 310.93 g/mol, is a CATO reference standard with documented purity and traceability.

2-(3,5-Dibromo-2-oxopyridin-1(2H)-yl)acetic acid (C7H5Br2NO3) 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.

As a certified reference material (CRM), 2-(3,5-Dibromo-2-oxopyridin-1(2H)-yl)acetic 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.
