Chemical Structure
Description
The occurrence of 2,3-dihydro-1-benzofuran-6-carbaldehyde is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 2,3-dihydro-1-benzofuran-6-carbaldehyde (CAS 55745-96-5), a certified reference material (molecular formula C9H14O2, MW 154.21 g/mol) for analytical method development and quality control.
The molecular framework of 2,3-dihydro-1-benzofuran-6-carbaldehyde (C9H14O2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage. 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 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.
As a certified reference material (CRM), 2,3-dihydro-1-benzofuran-6-carbaldehyde 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.
