Chemical Structure

Monoethyl Pyrophosphate CAS 20680-57-3 chemical structure

Description

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.

Monoethyl Pyrophosphate (CAS 20680-57-3), molecular formula C2H8O7P2 and molecular weight 206.03 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, Monoethyl Pyrophosphate (C2H8O7P2) contains a phosphate ester group, a carboxylic acid group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of -1.0, corresponding to approximately 0 ring(s) or double-bond equivalent(s). With a molecular weight of 206.03 g/mol, it falls into the medium-molecular-weight range.

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.
