Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 549.71 g/mol gives N-(4-chlorophenyl)-2-(1,1,2,2,3,3,4,4,5,5,6,6,6-tridecafluorohexyl)benzamide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
N-(4-chlorophenyl)-2-(1,1,2,2,3,3,4,4,5,5,6,6,6-tridecafluorohexyl)benzamide (CAS 680213-69-8), molecular formula C19H9ClF13NO and molecular weight 549.71 g/mol, is a CATO reference standard with documented purity and traceability.
N-(4-chlorophenyl)-2-(1,1,2,2,3,3,4,4,5,5,6,6,6-tridecafluorohexyl)benzamide (C19H9ClF13NO) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
