Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 303.57 g/mol gives Triclosan Methyl Ether distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Triclosan Methyl Ether (CAS 4640-01-1), a certified reference material (molecular formula C13H9Cl3O2, MW 303.57 g/mol) for analytical method development and quality control.
Triclosan Methyl Ether (C13H9Cl3O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, 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.
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.
