Description
CATO manufactures [2,2'-Bithiophen]-5-ylboronic 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.
CATO supplies [2,2'-Bithiophen]-5-ylboronic acid (CAS 132898-95-4), a certified reference material (molecular formula C8H7BO2S2, MW 210.08 g/mol) for analytical method development and quality control.
The molecular framework of [2,2'-Bithiophen]-5-ylboronic acid (C8H7BO2S2) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
