Chemical Structure
Description
The molecular framework of (3-Chlorothiophen-2-yl)trimethylstannane (C7H11ClSSn) is characterized by sulfur-containing functionality, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
