Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 414.30 g/mol gives Bis(4-methylumbelliferyl)phosphate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Bis(4-methylumbelliferyl)phosphate (CAS 51379-07-8), molecular formula C20H15O8P and molecular weight 414.30 g/mol, is a CATO reference standard with documented purity and traceability.
Bis(4-methylumbelliferyl)phosphate (C20H15O8P) contains a flavonoid core, a phosphate ester group, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
