Chemical Structure

N-(2-Hydroxyethyl)-N-methylstearamide CAS 35699-24-2 chemical structure

Description

The molecular framework of N-(2-Hydroxyethyl)-N-methylstearamide (C21H43NO2) is characterized by an amide group, a carboxylic acid 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

N-(2-Hydroxyethyl)-N-methylstearamide (CAS 35699-24-2), molecular formula C21H43NO2 and molecular weight 341.57 g/mol, is a CATO reference standard with documented purity and traceability.

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.

As a certified reference material (CRM), N-(2-Hydroxyethyl)-N-methylstearamide 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.
