Disodium Phenyl Phosphate Hydrate CAS 3279-54-7

Description

Compared with other compounds in its class, the molecular weight of 195.07 g/mol gives Disodium Phenyl Phosphate Hydrate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Disodium Phenyl Phosphate Hydrate (CAS 3279-54-7), molecular formula C6H5O4PNa and molecular weight 195.07 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, Disodium Phenyl Phosphate Hydrate (C6H5O4PNa) contains a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 4.5, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 195.07 g/mol, it falls into the medium-molecular-weight range. 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.
