Chemical Structure
Description
The molecular framework of 2-Chloro-N-((3-(5-ethylbenzo[d]oxazol-2-yl)phenyl)carbamothioyl)-4-fluorobenzamide (C23H17ClFN3O2S) is characterized by a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
2-Chloro-N-((3-(5-ethylbenzo[d]oxazol-2-yl)phenyl)carbamothioyl)-4-fluorobenzamide (CAS 593238-52-9), molecular formula C23H17ClFN3O2S and molecular weight 453.92 g/mol, is a CATO reference standard with documented purity and traceability.
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.
