Owing to an organic framework, 1,2-Bis(dimethylsilyl)benzene is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 194.42 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.
1,2-Bis(dimethylsilyl)benzene (CAS 17985-72-7), molecular formula C10H18Si2 and molecular weight 194.42 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.
