Chemical Structure

N-Ethylacetamide CAS 625-50-3 chemical structure

Description

As a certified reference material (CRM), N-Ethylacetamide 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.

N-Ethylacetamide (CAS 625-50-3), molecular formula C4H9NO and molecular weight 87.12 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of N-Ethylacetamide (C4H9NO) 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.
