Chemical Structure

25436-74-2 1,1,1,3,3,3-Hexaethyl-2-(triethylsilyl)trisilan-2-yl DTXSID70746448 CAS 25436-74-2 chemical structure

Description

Owing to an organic framework, 25436-74-2 1,1,1,3,3,3-Hexaethyl-2-(triethylsilyl)trisilan-2-yl DTXSID70746448 is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 374.90 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

25436-74-2 1,1,1,3,3,3-Hexaethyl-2-(triethylsilyl)trisilan-2-yl DTXSID70746448 (CAS 25436-74-2), molecular formula C18H46Si4 and molecular weight 374.90 g/mol, is a CATO reference standard with documented purity and traceability.

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.
