N-(3-chloro-4-fluorophenyl)-2-((4-chlorophenyl)thio)acetamide (CAS 303090-98-4), molecular formula C14H10Cl2FNOS and molecular weight 330.20 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C14H10Cl2FNOS, N-(3-chloro-4-fluorophenyl)-2-((4-chlorophenyl)thio)acetamide contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine/chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 330.20 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.
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.
