2-Bromo-3-chloro-5-(difluoromethyl)-4-(trifluoromethyl)pyridine CAS 1806033-01-1

Description

Compared with other compounds in its class, the molecular weight of 310.45 g/mol gives 2-Bromo-3-chloro-5-(difluoromethyl)-4-(trifluoromethyl)pyridine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2-Bromo-3-chloro-5-(difluoromethyl)-4-(trifluoromethyl)pyridine (CAS 1806033-01-1), molecular formula C7H2BrClF5N and molecular weight 310.45 g/mol, is a CATO reference standard with documented purity and traceability.

2-Bromo-3-chloro-5-(difluoromethyl)-4-(trifluoromethyl)pyridine (C7H2BrClF5N) contains a nitrile group, fluorine/chlorine/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. 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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
