Chemical Structure
Description
Based on its molecular formula D3O3P, Phosphorous Acid-D3DISCONTINUED contains deuterium isotope labeling, a phosphonate group; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 85.01 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry.
Phosphorous Acid-D3DISCONTINUED (CAS 57583-55-8) is a high-purity analytical reference standard with the molecular formula D3O3P and a molecular weight of 85.01 g/mol.
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.
