Chemical Structure

n-Decyldimethylmethoxysilane CAS 4170-50-7 chemical structure

Description

n-Decyldimethylmethoxysilane (CAS 4170-50-7), molecular formula C2H3Br2Cl3Si and molecular weight 321.30 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of n-Decyldimethylmethoxysilane (C2H3Br2Cl3Si) is characterized by chlorine/bromine substitution. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
