Chemical Structure
Description
As a certified reference material (CRM), n-(1,1-Dioxidotetrahydrothiophen-3-yl)benzamide meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
n-(1,1-Dioxidotetrahydrothiophen-3-yl)benzamide (CAS 17153-58-1), molecular formula C11H13NO3S and molecular weight 239.29 g/mol, is a CATO reference standard with documented purity and traceability.
n-(1,1-Dioxidotetrahydrothiophen-3-yl)benzamide (C11H13NO3S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; 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).
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.
