2-Propenoic acid, 1,1'-[phosphinicobis(oxy-2,1-ethanediyl)] ester CAS 40074-34-8

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.

2-Propenoic acid, 1,1'-[phosphinicobis(oxy-2,1-ethanediyl)] ester (CAS 40074-34-8), molecular formula C10H15O8P and molecular weight 294.20 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a carbohydrate-derived structure, a phosphate ester group, 2-Propenoic acid, 1,1'-[phosphinicobis(oxy-2,1-ethanediyl)] ester is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 294.20 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).

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.
