Chemical Structure
Description
2-Benzhydryl-3-phenyl-2,5-dihydroisoxazole (CAS 754991-55-4), molecular formula C22H19NO and molecular weight 313.39 g/mol, is a CATO reference standard with documented purity and traceability.
2-Benzhydryl-3-phenyl-2,5-dihydroisoxazole (C22H19NO) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. 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), 2-Benzhydryl-3-phenyl-2,5-dihydroisoxazole 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.
