Chemical Structure
Description
(Morpholinomethylene)bis(phosphonic acid) (CAS 32545-75-8), molecular formula C17H14O7 and molecular weight 330.29 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C17H14O7, (Morpholinomethylene)bis(phosphonic acid) contains a flavonoid core, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 330.29 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
