Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 487.64 g/mol gives Triclosan O-beta-D-Glucuronide sodium distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Triclosan O-beta-D-Glucuronide sodium (CAS CATO-C4X-25049), molecular formula C18H14Cl3O8Na and molecular weight 487.64 g/mol, is a CATO reference standard with documented purity and traceability.
Triclosan O-beta-D-Glucuronide sodium (C18H14Cl3O8Na) contains a salt form, a flavonoid core, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
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.
