Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 260.22 g/mol gives 2-(Diphenylphosphoryl)acetic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2-(Diphenylphosphoryl)acetic acid (CAS 1831-63-6), molecular formula C14H13O3P and molecular weight 260.22 g/mol, is a CATO reference standard with documented purity and traceability.
2-(Diphenylphosphoryl)acetic acid (C14H13O3P) contains a phosphonate group, a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. It is notably hygroscopic, 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).
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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
