Chemical Structure
Description
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.
CATO supplies N-Methyl-4-nitro-3-((tetrahydrofuran-3-yl)oxy)benzamide (CAS 917909-67-2), a certified reference material (molecular formula C12H14N2O5, MW 266.25 g/mol) for analytical method development and quality control.
Based on its molecular formula C12H14N2O5, N-Methyl-4-nitro-3-((tetrahydrofuran-3-yl)oxy)benzamide contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 266.25 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.
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.
