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.
2-(Benzo[d]oxazol-2-ylthio)-N-(sec-butyl)acetamide (CAS 923169-72-6), molecular formula C13H16N2O2S and molecular weight 264.34 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C13H16N2O2S, 2-(Benzo[d]oxazol-2-ylthio)-N-(sec-butyl)acetamide contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 264.34 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).
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.
