Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
2-Bromo-2-((4-chlorophenyl)thio)-1-(2,4-dichlorophenyl)ethan-1-one (CAS 439097-08-2), molecular formula C14H8BrCl3OS and molecular weight 410.54 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine/bromine substitution, a polycyclic aromatic system, 2-Bromo-2-((4-chlorophenyl)thio)-1-(2,4-dichlorophenyl)ethan-1-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 410.54 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
