Chemical Structure
Description
N-(tert-butyl)-3-nitrobenzamide (CAS 10222-93-2), molecular formula C11H14N2O3 and molecular weight 222.24 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C11H14N2O3, N-(tert-butyl)-3-nitrobenzamide 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 222.24 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
