Chemical Structure

1,8-Octanediphosphonic Acid CAS 5943-66-8 chemical structure

Description

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

CATO supplies 1,8-Octanediphosphonic Acid (CAS 5943-66-8), a certified reference material (molecular formula C8H20O6P2, MW 274.19 g/mol) for analytical method development and quality control.

Based on its molecular formula C8H20O6P2, 1,8-Octanediphosphonic Acid contains a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 274.19 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry.

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.
