Chemical Structure
Description
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.
3,4-Dibromo-2-(((2-(3-chlorophenyl)benzo[d]oxazol-5-yl)imino)methyl)-6-methoxyphenol (CAS 330564-04-0), molecular formula C21H13Br2ClN2O3 and molecular weight 536.60 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 3,4-Dibromo-2-(((2-(3-chlorophenyl)benzo[d]oxazol-5-yl)imino)methyl)-6-methoxyphenol (C21H13Br2ClN2O3) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine/bromine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
