Chemical Structure

Phosphonic acid-<SUP>18</SUP>O<SUB>3</SUB> CAS 105582-58-9 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 88.00 g/mol gives Phosphonic acid-<SUP>18</SUP>O<SUB>3</SUB> distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Phosphonic acid-<SUP>18</SUP>O<SUB>3</SUB> (CAS 105582-58-9), a certified reference material (molecular formula H3[18O]3P, MW 88.00 g/mol) for analytical method development and quality control.

Structurally, Phosphonic acid-<SUP>18</SUP>O<SUB>3</SUB> (H3[18O]3P) contains organophosphorus functionality. The molecule exhibits a degree of unsaturation (DBE) of 0, corresponding to approximately 0 ring(s) or double-bond equivalent(s). With a molecular weight of 88.00 g/mol, it falls into the low-molecular-weight range.

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.
