Chemical Structure

Pyrophosphoric acid CAS 2466-09-3 chemical structure

Description

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.

Pyrophosphoric acid (CAS 2466-09-3), molecular formula H4O7P2 and molecular weight 177.98 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula H4O7P2, Pyrophosphoric acid contains a phosphate ester group; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 177.98 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry.

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.
