Chemical Structure
Description
3-Fluoro-4-((tetrahydro-2H-pyran-4-yl)oxy)benzenesulfonyl chloride (C11H12ClFO4S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system. It is notably hygroscopic, 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
3-Fluoro-4-((tetrahydro-2H-pyran-4-yl)oxy)benzenesulfonyl chloride (CAS 1343859-00-6), molecular formula C11H12ClFO4S and molecular weight 294.73 g/mol, is a CATO reference standard with documented purity and traceability.
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.
As a certified reference material (CRM), 3-Fluoro-4-((tetrahydro-2H-pyran-4-yl)oxy)benzenesulfonyl chloride 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.
