Description
As a certified reference material (CRM), 5-Acetyl-2,3-Dihydro-1-Benzofuran 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.
5-Acetyl-2,3-Dihydro-1-Benzofuran (CAS 90843-31-5) is a high-purity analytical reference standard with the molecular formula C10H10O2 and a molecular weight of 162.19 g/mol.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, 5-Acetyl-2,3-Dihydro-1-Benzofuran is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 162.19 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
