CATO supplies Sodium 2,6-dibromo-4-(3-(3,5-dibromo-4-hydroxy-2-methylphenyl)-1,1-dioxido-3H-benzo[c][1,2]oxathiol-3-yl)-3-methylphenolate (CAS 67763-24-0), a certified reference material (molecular formula C21H13Br4O5SNa, MW 720.00 g/mol) for analytical method development and quality control.
The molecular framework of Sodium 2,6-dibromo-4-(3-(3,5-dibromo-4-hydroxy-2-methylphenyl)-1,1-dioxido-3H-benzo[c][1,2]oxathiol-3-yl)-3-methylphenolate (C21H13Br4O5SNa) is characterized by a salt form, a flavonoid core, a sulfone group, a hydroxyl group, an ether linkage, bromine substitution. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
