Chemical Structure
Description
5-Ethynyl-2,3-dihydro-1-benzofuran (CAS 132464-87-0), molecular formula C10H8O and molecular weight 144.17 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 5-Ethynyl-2,3-dihydro-1-benzofuran (C10H8O) is characterized by a hydroxyl group, an ether linkage, 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures 5-Ethynyl-2,3-dihydro-1-benzofuran 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.
