Chemical Structure

Etidronic Acid Monohydrate CAS 25211-86-3 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 224.04 g/mol gives Etidronic Acid Monohydrate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Etidronic Acid Monohydrate (CAS 25211-86-3), molecular formula C2H8O7P2H2O and molecular weight 224.04 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C2H8O7P2H2O, Etidronic Acid Monohydrate contains a phosphate ester group, a carboxylic acid group, an ether linkage; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 224.04 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

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.
