Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 368.64 g/mol gives (11-Bromoundecyl)trichlorosilane distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
(11-Bromoundecyl)trichlorosilane (CAS 79769-48-5) is a high-purity analytical reference standard with the molecular formula C11H22BrCl3Si and a molecular weight of 368.64 g/mol.
The molecular framework of (11-Bromoundecyl)trichlorosilane (C11H22BrCl3Si) is characterized by chlorine/bromine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), 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.
CATO manufactures (11-Bromoundecyl)trichlorosilane under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
