Chemical Structure

Sodium octacosanoate CAS 25728-82-9 chemical structure

Description

CATO manufactures Sodium octacosanoate 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.

Sodium octacosanoate (CAS 25728-82-9), molecular formula C28H55O2Na and molecular weight 446.74 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of Sodium octacosanoate (C28H55O2Na) 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.

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.
