Chemical Structure
Description
CATO supplies (3-Nitro-4-phenoxyphenyl)methyl N-[3-(trifluoromethyl)phenyl]carbamate (CAS 338960-92-2), a certified reference material (molecular formula C21H15F3N2O5, MW 432.35 g/mol) for analytical method development and quality control.
Based on its molecular formula C21H15F3N2O5, (3-Nitro-4-phenoxyphenyl)methyl N-[3-(trifluoromethyl)phenyl]carbamate contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 432.35 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
