Chemical Structure
Description
As a certified reference material (CRM), 4-Bromo-N-butyl-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.
4-Bromo-N-butyl-N-(1,1-dioxidotetrahydrothiophen-3-yl)benzamide (CAS 874787-66-3), molecular formula C15H20BrNO3S and molecular weight 374.29 g/mol, is a CATO reference standard with documented purity and traceability.
4-Bromo-N-butyl-N-(1,1-dioxidotetrahydrothiophen-3-yl)benzamide (C15H20BrNO3S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, bromine substitution. Halogen substitution raises its density and boiling point, 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. 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.
