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.
2-(2-Bromoethyl)-1,3-dichlorobenzene (CAS 40173-94-2), molecular formula C8H7BrCl2 and molecular weight 253.95 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to chlorine/bromine substitution, an aromatic ring system, 2-(2-Bromoethyl)-1,3-dichlorobenzene is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 253.95 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
