Chemical Structure
Description
55644-08-1 Dimethylbis(alpha-bromoisopropyl)silane (CAS 55644-08-1) is a high-purity analytical reference standard with the molecular formula C8H18Br2Si and a molecular weight of 302.12 g/mol.
The molecular framework of 55644-08-1 Dimethylbis(alpha-bromoisopropyl)silane (C8H18Br2Si) is characterized by bromine substitution. 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. 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.
