Chemical Structure

3-Bromo-2,3-dimethyl-1-butene DISCONTINUED CAS 109929-23-9 chemical structure

Description

3-Bromo-2,3-dimethyl-1-butene DISCONTINUED (CAS 109929-23-9) is a high-purity analytical reference standard with the molecular formula C6H11Br and a molecular weight of 163.06 g/mol.

3-Bromo-2,3-dimethyl-1-butene DISCONTINUED (C6H11Br) contains bromine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
