Chemical Structure
Description
5-Fluoro-2-(p-tolylethynyl)benzaldehyde (CAS 1322091-23-5), molecular formula C16H11FO and molecular weight 238.26 g/mol, is a CATO reference standard with documented purity and traceability.
5-Fluoro-2-(p-tolylethynyl)benzaldehyde (C16H11FO) contains a hydroxyl group, an ether linkage, fluorine substitution, a polycyclic aromatic system. 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).
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), 5-Fluoro-2-(p-tolylethynyl)benzaldehyde 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.
