Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 521.92 g/mol gives 2,5-Di(trimethyltin)thieno[3,2-b]thiophene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 2,5-Di(trimethyltin)thieno[3,2-b]thiophene (CAS 502764-57-0), a certified reference material (molecular formula C14H20S3Sn2, MW 521.92 g/mol) for analytical method development and quality control.
The molecular framework of 2,5-Di(trimethyltin)thieno[3,2-b]thiophene (C14H20S3Sn2) is characterized by sulfur-containing functionality, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures 2,5-Di(trimethyltin)thieno[3,2-b]thiophene under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
