Chemical Structure

2-Bromo-4-(perfluoroethyl)pyridine CAS 1816286-31-3 chemical structure

Description

The occurrence of 2-Bromo-4-(perfluoroethyl)pyridine is closely related to a nitrile group, fluorine/bromine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

2-Bromo-4-(perfluoroethyl)pyridine (CAS 1816286-31-3) is a high-purity analytical reference standard with the molecular formula C7H3BrF5N and a molecular weight of 276.00 g/mol.

2-Bromo-4-(perfluoroethyl)pyridine (C7H3BrF5N) contains a nitrile group, fluorine/bromine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; 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.

As a certified reference material (CRM), 2-Bromo-4-(perfluoroethyl)pyridine 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.
