Chemical Structure
Description
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.
4,4-Dihexyl-4H-silolo[3,2-b:4,5-b']dithiophene (CAS 906372-08-5), molecular formula C20H30S2Si and molecular weight 362.67 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to sulfur-containing functionality, an aromatic ring system, 4,4-Dihexyl-4H-silolo[3,2-b:4,5-b']dithiophene is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 362.67 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.
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.
