(E)-3-(4-Ethylbenzylidene)-5-methylpyrrolidin-2-one CAS 679818-35-0

Description

The occurrence of (E)-3-(4-Ethylbenzylidene)-5-methylpyrrolidin-2-one is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

(E)-3-(4-Ethylbenzylidene)-5-methylpyrrolidin-2-one (CAS 679818-35-0), molecular formula C14H17NO and molecular weight 215.29 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, (E)-3-(4-Ethylbenzylidene)-5-methylpyrrolidin-2-one is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 215.29 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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), (E)-3-(4-Ethylbenzylidene)-5-methylpyrrolidin-2-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.
