Ethene-1,1-diylbis(phosphonic acid) CAS 34162-79-3

Description

Compared with other compounds in its class, the molecular weight of 188.01 g/mol gives Ethene-1,1-diylbis(phosphonic acid) distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Ethene-1,1-diylbis(phosphonic acid) (CAS 34162-79-3), molecular formula C2H6O6P2 and molecular weight 188.01 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a phosphate ester group, a carboxylic acid group, an ether linkage, Ethene-1,1-diylbis(phosphonic acid) is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 188.01 g/mol — guide the selection of appropriate sample preparation and analytical techniques.

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.
