Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
1,5-Dibromo-2-chloro-3-isopropylbenzene (CAS 1160575-03-0) is a high-purity analytical reference standard with the molecular formula C9H9Br2Cl and a molecular weight of 312.43 g/mol.
Owing to chlorine/bromine substitution, an aromatic ring system, 1,5-Dibromo-2-chloro-3-isopropylbenzene is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 312.43 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.
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.
