Chemical Structure

2-(2-Bromo-6-(difluoromethyl)-3-nitropyridin-4-yl)acetic acid CAS 1806916-75-5 chemical structure

Description

The occurrence of 2-(2-Bromo-6-(difluoromethyl)-3-nitropyridin-4-yl)acetic acid is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

2-(2-Bromo-6-(difluoromethyl)-3-nitropyridin-4-yl)acetic acid (CAS 1806916-75-5) is a high-purity analytical reference standard with the molecular formula C8H5BrF2N2O4 and a molecular weight of 311.04 g/mol.

2-(2-Bromo-6-(difluoromethyl)-3-nitropyridin-4-yl)acetic acid (C8H5BrF2N2O4) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/bromine substitution. 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. 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.

As a certified reference material (CRM), 2-(2-Bromo-6-(difluoromethyl)-3-nitropyridin-4-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.
