Chemical Structure
Description
3-((Diphenoxyphosphoryl)oxy)benzyl butyrate (CAS 161179-36-8) is a high-purity analytical reference standard with the molecular formula C23H23O6P and a molecular weight of 426.40 g/mol.
3-((Diphenoxyphosphoryl)oxy)benzyl butyrate (C23H23O6P) contains a flavonoid core, a phosphate ester group, a hydroxyl group, an ether linkage. 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).
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-((Diphenoxyphosphoryl)oxy)benzyl butyrate 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.
