Chemical Structure

18-Mercaptooctadecanoic acid CAS 600730-11-8 chemical structure

Description

18-Mercaptooctadecanoic acid (CAS 600730-11-8), molecular formula C18H36O2S and molecular weight 316.54 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 18-Mercaptooctadecanoic acid (C18H36O2S) is characterized by a sulfone 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.

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), 18-Mercaptooctadecanoic acid 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.
