1,4-Dibromo-2,5-bis[2-(trimethylsilyl)ethynyl]benzene CAS 478190-79-3

Description

Compared with other compounds in its class, the molecular weight of 428.31 g/mol gives 1,4-Dibromo-2,5-bis[2-(trimethylsilyl)ethynyl]benzene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 1,4-Dibromo-2,5-bis[2-(trimethylsilyl)ethynyl]benzene (CAS 478190-79-3), a certified reference material (molecular formula C16H20Br2Si2, MW 428.31 g/mol) for analytical method development and quality control.

Based on its molecular formula C16H20Br2Si2, 1,4-Dibromo-2,5-bis[2-(trimethylsilyl)ethynyl]benzene contains bromine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 428.31 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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), 1,4-Dibromo-2,5-bis[2-(trimethylsilyl)ethynyl]benzene 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.
