Chemical Structure
Description
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine substitution, 2,4-Difluoro-N,N-dimethylaniline is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 157.16 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
CATO supplies 2,4-Difluoro-N,N-dimethylaniline (CAS 78409-21-9), a certified reference material (molecular formula C8H9F2N, MW 157.16 g/mol) for analytical method development and quality control.
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.
