Chemical Structure

Unsaturated fatty acids, C18, dimers CAS 61788-89-4 chemical structure

Description

Unsaturated fatty acids, C18, dimers (CAS 61788-89-4), molecular formula C36H68O4 and molecular weight 564.92 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of Unsaturated fatty acids, C18, dimers (C36H68O4) 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.

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.
