Chemical Structure
Description
The occurrence of 7399-00-0 Octadecyltriethoxysilane S12276 n-octadecyltriethoxysilane octadecyl triethoxysilane triethoxy(octadecyl)silane is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
7399-00-0 Octadecyltriethoxysilane S12276 n-octadecyltriethoxysilane octadecyl triethoxysilane triethoxy(octadecyl)silane (CAS 7399-00-0) is a high-purity analytical reference standard with the molecular formula C24H52O3Si and a molecular weight of 416.75 g/mol.
7399-00-0 Octadecyltriethoxysilane S12276 n-octadecyltriethoxysilane octadecyl triethoxysilane triethoxy(octadecyl)silane (C24H52O3Si) contains a carboxylic acid group, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
