16173-49-2 CTK0E6450 Peroxide, bis[4-(chloromethyl)benzoyl] (CAS 16173-49-2), molecular formula C16H12Cl2O4 and molecular weight 339.17 g/mol, is a CATO reference standard with documented purity and traceability.
16173-49-2 CTK0E6450 Peroxide, bis[4-(chloromethyl)benzoyl] (C16H12Cl2O4) contains a flavonoid core, a hydroxyl group, an ether linkage, chlorine substitution. 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.
