Dimethoxy(methyl)(octadecyl)silane CAS 70851-50-2

Description

The occurrence of Dimethoxy(methyl)(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.

CATO supplies Dimethoxy(methyl)(octadecyl)silane (CAS 70851-50-2), a certified reference material (molecular formula C21H46O2Si, MW 358.67 g/mol) for analytical method development and quality control.

Dimethoxy(methyl)(octadecyl)silane (C21H46O2Si) 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.
