((2-bromophenyl)ethynyl)trimethylsilane (2-Bromophenylethynyl)trimethylsilane 38274-16-7 CAS 38274-16-7

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including ((2-bromophenyl)ethynyl)trimethylsilane (2-Bromophenylethynyl)trimethylsilane 38274-16-7.

((2-bromophenyl)ethynyl)trimethylsilane (2-Bromophenylethynyl)trimethylsilane 38274-16-7 (CAS 38274-16-7) is a high-purity analytical reference standard with the molecular formula C11H19BrSi and a molecular weight of 259.26 g/mol.

Based on its molecular formula C11H19BrSi, ((2-bromophenyl)ethynyl)trimethylsilane (2-Bromophenylethynyl)trimethylsilane 38274-16-7 contains bromine substitution; these features give the compound characteristic molecular-ion distribution patterns in mass spectrometry. The molecular weight of 259.26 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.

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.
