Naphthalen-2-yl diphenyl phosphate CAS 18872-49-6

Description

The occurrence of Naphthalen-2-yl diphenyl phosphate is closely related to a flavonoid core, a phosphate ester group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Naphthalen-2-yl diphenyl phosphate (CAS 18872-49-6), molecular formula C22H17O4P and molecular weight 376.34 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, Naphthalen-2-yl diphenyl phosphate (C22H17O4P) contains a flavonoid core, a phosphate ester group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 14.5, corresponding to approximately 14 ring(s) or double-bond equivalent(s). With a molecular weight of 376.34 g/mol, it falls into the moderately-high-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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), Naphthalen-2-yl diphenyl phosphate 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.
