4,4-Didecyl-4H-silolo[3,2-b:4,5-b′]dithiophene CAS 1500083-25-9

Description

4,4-Didecyl-4H-silolo[3,2-b:4,5-b′]dithiophene (CAS 1500083-25-9), molecular formula C28H46S2Si and molecular weight 474.88 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 4,4-Didecyl-4H-silolo[3,2-b:4,5-b′]dithiophene (C28H46S2Si) contains sulfur-containing functionality, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 474.88 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.

As a certified reference material (CRM), 4,4-Didecyl-4H-silolo[3,2-b:4,5-b′]dithiophene meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
