2,4-Difluoro-N-methylaniline CAS 138564-16-6

Description

Compared with other compounds in its class, the molecular weight of 143.13 g/mol gives 2,4-Difluoro-N-methylaniline distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2,4-Difluoro-N-methylaniline (CAS 138564-16-6), molecular formula C7H7F2N and molecular weight 143.13 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrile group, fluorine substitution, an aromatic ring system, 2,4-Difluoro-N-methylaniline is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 143.13 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.

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.
