Chemical Structure
Description
1-Ethylpyridin-2(1H)-one (CAS 13337-79-6), molecular formula C7H9NO and molecular weight 123.15 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to an amide group, a hydroxyl group, an ether linkage, an aromatic ring system, 1-Ethylpyridin-2(1H)-one is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 123.15 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).
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), 1-Ethylpyridin-2(1H)-one 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.
