Chemical Structure

N-Ethyl-4-methoxy-N-(3-methylphenyl)benzamide CAS 959303-25-4 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.

N-Ethyl-4-methoxy-N-(3-methylphenyl)benzamide (CAS 959303-25-4) is a high-purity analytical reference standard with the molecular formula C17H19NO2 and a molecular weight of 269.34 g/mol.

Based on its molecular formula C17H19NO2, N-Ethyl-4-methoxy-N-(3-methylphenyl)benzamide contains a steroid core, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 269.34 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
