Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 350.09 g/mol gives 1,3-Dibromo-2-butoxy-5-isopropylbenzene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 1,3-Dibromo-2-butoxy-5-isopropylbenzene (CAS 2379321-57-8), a certified reference material (molecular formula C13H18Br2O, MW 350.09 g/mol) for analytical method development and quality control.
Structurally, 1,3-Dibromo-2-butoxy-5-isopropylbenzene (C13H18Br2O) contains a hydroxyl group, an ether linkage, 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 350.09 g/mol, it falls into the moderately-high-molecular-weight range. 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).
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.
