Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 5,5'-Dibromo-[2,2'-bithiophene]-4,4'-dicarboxylic acid (CAS 1696391-77-1), a certified reference material (molecular formula C10H4Br2O4S2, MW 412.07 g/mol) for analytical method development and quality control.
The molecular framework of 5,5'-Dibromo-[2,2'-bithiophene]-4,4'-dicarboxylic acid (C10H4Br2O4S2) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
CATO manufactures 5,5'-Dibromo-[2,2'-bithiophene]-4,4'-dicarboxylic acid 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.
