Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
β-Estradiol 17-(β-D-glucuronide) sodium salt (CAS CATO-C3D-1941), molecular formula C24H31NaO8 and molecular weight 470.49 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C24H31NaO8, β-Estradiol 17-(β-D-glucuronide) sodium salt 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 470.49 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
