Chemical Structure
Description
CATO supplies 4-Chloro-3,5-dibromoisopropylbenzene (CAS 1160574-99-1), a certified reference material (molecular formula C9H9Br2Cl, MW 312.43 g/mol) for analytical method development and quality control.
Structurally, 4-Chloro-3,5-dibromoisopropylbenzene (C9H9Br2Cl) contains chlorine/bromine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 312.43 g/mol, it falls into the moderately-high-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
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.
