Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 271.22 g/mol gives (5-Bromopentyl)trimethoxysilane distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
(5-Bromopentyl)trimethoxysilane (CAS 773893-02-0) is a high-purity analytical reference standard with the molecular formula C8H19BrO3Si and a molecular weight of 271.22 g/mol.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, (5-Bromopentyl)trimethoxysilane is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 271.22 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
As a certified reference material (CRM), (5-Bromopentyl)trimethoxysilane meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
