Chemical Structure

(2E)-N-(4-Methylphenyl)-3-(pyrrolidin-1-yl)but-2-enamide CAS 337921-22-9 chemical structure

Description

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.

(2E)-N-(4-Methylphenyl)-3-(pyrrolidin-1-yl)but-2-enamide (CAS 337921-22-9), molecular formula C15H20N2O and molecular weight 244.33 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, (2E)-N-(4-Methylphenyl)-3-(pyrrolidin-1-yl)but-2-enamide is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 244.33 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
