Chemical Structure
Description
2-Bromo-1-(tert-butyl)-4-chlorobenzene (CAS 1369776-71-5), molecular formula C10H12BrCl and molecular weight 247.56 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C10H12BrCl, 2-Bromo-1-(tert-butyl)-4-chlorobenzene contains chlorine/bromine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 247.56 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
