Chemical Structure

Heneicosanoic Acid-Ethyl Ester CAS 28898-67-1 chemical structure

Description

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.

Heneicosanoic Acid-Ethyl Ester (CAS 28898-67-1), molecular formula C23H46O2 and molecular weight 354.61 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of Heneicosanoic Acid-Ethyl Ester (C23H46O2) is characterized by 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.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
