Chemical Structure
Description
The occurrence of 7-Fluoro-2,3-dihydrobenzofuran is closely related to a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 7-Fluoro-2,3-dihydrobenzofuran (CAS 1072153-64-0), a certified reference material (molecular formula C8H7FO, MW 138.14 g/mol) for analytical method development and quality control.
Owing to a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system, 7-Fluoro-2,3-dihydrobenzofuran is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 138.14 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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), 7-Fluoro-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.
