Chemical Structure

Diphosphoric acid, zinc salt (1:2) CAS 7446-26-6 chemical structure

Description

The occurrence of Diphosphoric acid, zinc salt (1:2) is closely related to a phosphate ester group in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Diphosphoric acid, zinc salt (1:2) (CAS 7446-26-6), molecular formula O7P2Zn and molecular weight 239.32 g/mol, is a CATO reference standard with documented purity and traceability.

Diphosphoric acid, zinc salt (1:2) (O7P2Zn) contains a phosphate ester group. It is notably hygroscopic; these physicochemical properties determine the optimal preparation and storage of its standard solutions.

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.
