Compared with other compounds in its class, the molecular weight of 356.70 g/mol gives Ethoxydimethyl(octadecyl)silane distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Ethoxydimethyl(octadecyl)silane (CAS 97330-35-3), a certified reference material (molecular formula C22H48OSi, MW 356.70 g/mol) for analytical method development and quality control.
Structurally, Ethoxydimethyl(octadecyl)silane (C22H48OSi) contains a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of -1.0, corresponding to approximately 0 ring(s) or double-bond equivalent(s). With a molecular weight of 356.70 g/mol, it falls into the moderately-high-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
