Chemical Structure
Description
2,3,6-Trifluorobenzamide (CAS 207986-22-9) is a high-purity analytical reference standard with the molecular formula C7H4F3NO and a molecular weight of 175.11 g/mol.
Owing to an amide group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system, 2,3,6-Trifluorobenzamide is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 175.11 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.
