Chemical Structure
Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
2-Ethyl-3-methylbenzofuran (CAS 80079-25-0), molecular formula C11H12O and molecular weight 160.21 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a hydroxyl group, an ether linkage, an aromatic ring system, 2-Ethyl-3-methylbenzofuran is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 160.21 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).
As a certified reference material (CRM), 2-Ethyl-3-methylbenzofuran 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.
