ethyl 2,5-dibromo-6-nonylthieno[3,2-b]thiophene-3-carboxylate (CAS 2105955-68-6), molecular formula C18H28O4S2Sn2 and molecular weight 609.96 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of ethyl 2,5-dibromo-6-nonylthieno[3,2-b]thiophene-3-carboxylate (C18H28O4S2Sn2) is characterized by a steroid core, a sulfone group, a hydroxyl group, an ether linkage. 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.
