Chemical Structure

N-Methylacetamide CAS 79-16-3 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 73.09 g/mol gives N-Methylacetamide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

N-Methylacetamide (CAS 79-16-3) is a high-purity analytical reference standard with the molecular formula C3H7NO and a molecular weight of 73.09 g/mol.

The molecular framework of N-Methylacetamide (C3H7NO) is characterized by an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

CATO manufactures N-Methylacetamide under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
