Chemical Structure

1-Methyl-1,1,2,2,2-pentaphenyldisilane CAS 1450-22-2 chemical structure

Description

CATO supplies 1-Methyl-1,1,2,2,2-pentaphenyldisilane (CAS 1450-22-2), a certified reference material (molecular formula C31H28Si2, MW 456.73 g/mol) for analytical method development and quality control.

Structurally, 1-Methyl-1,1,2,2,2-pentaphenyldisilane (C31H28Si2) contains a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 18.0, corresponding to approximately 18 ring(s) or double-bond equivalent(s). With a molecular weight of 456.73 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.

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.
