Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
5,5''-Dibromo-2,2':5',2''-terthiophene (CAS 98057-08-0), molecular formula C12H6Br2S3 and molecular weight 406.18 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 5,5''-Dibromo-2,2':5',2''-terthiophene (C12H6Br2S3) is characterized by sulfur-containing functionality, bromine substitution, 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).
CATO manufactures 5,5''-Dibromo-2,2':5',2''-terthiophene 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.
