Chemical Structure
Description
2-Fluoro-N-((1-(thiophen-2-yl)cyclopentyl)methyl)benzamide (CAS 1058394-29-8), molecular formula C17H18FNOS and molecular weight 303.39 g/mol, is a CATO reference standard with documented purity and traceability.
2-Fluoro-N-((1-(thiophen-2-yl)cyclopentyl)methyl)benzamide (C17H18FNOS) 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
