Chemical Structure
Description
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.
((1-Hydroxycycloheptyl)methyl)diphenylphosphine oxide (CAS 89358-61-2), molecular formula C20H25O2P and molecular weight 328.39 g/mol, is a CATO reference standard with documented purity and traceability.
((1-Hydroxycycloheptyl)methyl)diphenylphosphine oxide (C20H25O2P) contains a steroid core, organophosphorus functionality, a hydroxyl group, an ether linkage. 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).
As a certified reference material (CRM), ((1-Hydroxycycloheptyl)methyl)diphenylphosphine oxide 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.
