Chemical Structure
Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
Tetrahydrofuran-2,5-dicarboxylic Acid (CAS 2240-81-5) is a high-purity analytical reference standard with the molecular formula C6H8O5 and a molecular weight of 160.12 g/mol.
Tetrahydrofuran-2,5-dicarboxylic Acid (C6H8O5) contains a carbohydrate-derived structure. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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 Tetrahydrofuran-2,5-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.
