Chemical Structure
Description
7787-87-3 (1-Chloroethyl)trimethylsilane Silane, (1-chloroethyl)trimethyl- 1-Chloroethyltrimethylsilane EINECS 232-135-8 (CAS 7787-87-3) is a high-purity analytical reference standard with the molecular formula C5H13ClSi and a molecular weight of 136.70 g/mol.
Based on its molecular formula C5H13ClSi, 7787-87-3 (1-Chloroethyl)trimethylsilane Silane, (1-chloroethyl)trimethyl- 1-Chloroethyltrimethylsilane EINECS 232-135-8 contains chlorine substitution; these features give the compound characteristic molecular-ion distribution patterns in mass spectrometry. The molecular weight of 136.70 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
