Description

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.

3,3’-Dibromo-5,5’-bis(trimethylsilyl)-2,2’-bithiophene (CAS 207742-50-5) is a high-purity analytical reference standard with the molecular formula C14H20Br2S2Si2 and a molecular weight of 468.42 g/mol.

Structurally, 3,3’-Dibromo-5,5’-bis(trimethylsilyl)-2,2’-bithiophene (C14H20Br2S2Si2) contains sulfur-containing functionality, bromine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 468.42 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.
