Chemical Structure
Description
The occurrence of Estramustine Disodium Phosphate is closely related to a salt form, a flavonoid core, an amide group, a phosphate ester group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Estramustine Disodium Phosphate (CAS 52205-73-9) is a high-purity analytical reference standard with the molecular formula C23H30Cl2NO6PNa and a molecular weight of 541.36 g/mol.
Based on its molecular formula C23H30Cl2NO6PNa, Estramustine Disodium Phosphate contains a salt form, a flavonoid core, an amide group, a phosphate ester group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 541.36 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.
