Chemical Structure
Description
The occurrence of Tetracycline phosphate complex is closely related to a flavonoid core, an amide group, a phosphate ester group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Tetracycline phosphate complex (CAS 1336-20-5), molecular formula C22H24N2O8HO3PO3PNa and molecular weight 626.38 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C22H24N2O8HO3PO3PNa, Tetracycline phosphate complex contains a flavonoid core, an amide group, a phosphate ester group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 626.38 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.
