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.
4-Amino-5-benzoyl-2-((3-fluorobenzyl)thio)thiophene-3-carbonitrile (CAS 478081-56-0), molecular formula C19H13FN2OS2 and molecular weight 368.45 g/mol, is a CATO reference standard with documented purity and traceability.
4-Amino-5-benzoyl-2-((3-fluorobenzyl)thio)thiophene-3-carbonitrile (C19H13FN2OS2) contains a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
