Chemical Structure
Description
Owing to a hydroxyl group, an ether linkage, an aromatic ring system, 2,3-Dihydrobenzofuran is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 120.15 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
CATO supplies 2,3-Dihydrobenzofuran (CAS 496-16-2), a certified reference material (molecular formula C8H8O, MW 120.15 g/mol) for analytical method development and quality control.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 2,3-Dihydrobenzofuran meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
