2-Bromo-3-difluoromethoxy-4-nitrotoluene CAS 1807116-34-2

Description

Compared with other compounds in its class, the molecular weight of 282.04 g/mol gives 2-Bromo-3-difluoromethoxy-4-nitrotoluene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2-Bromo-3-difluoromethoxy-4-nitrotoluene (CAS 1807116-34-2), molecular formula C8H6BrF2NO3 and molecular weight 282.04 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C8H6BrF2NO3, 2-Bromo-3-difluoromethoxy-4-nitrotoluene contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 282.04 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
