Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 221.25 g/mol gives N-(2-methoxybenzyl)-3-oxobutanamide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
N-(2-methoxybenzyl)-3-oxobutanamide (CAS 331713-77-0), molecular formula C12H15NO3 and molecular weight 221.25 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of N-(2-methoxybenzyl)-3-oxobutanamide (C12H15NO3) is characterized by an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
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.
