Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 233.53 g/mol gives 2-Bromo-4-chloro-1-isopropylbenzene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2-Bromo-4-chloro-1-isopropylbenzene (CAS 1369828-32-9), molecular formula C9H10BrCl and molecular weight 233.53 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-Bromo-4-chloro-1-isopropylbenzene (C9H10BrCl) is characterized by chlorine/bromine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional 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.
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.
