Chemical Structure

Dihomo-Gamma-Linolenic Acid CAS 1783-84-2 chemical structure

Description

Dihomo-Gamma-Linolenic Acid (C20H34O2) contains a steroid core, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

Dihomo-Gamma-Linolenic Acid (CAS 1783-84-2) is a high-purity analytical reference standard with the molecular formula C20H34O2 and a molecular weight of 306.48 g/mol.

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), Dihomo-Gamma-Linolenic 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.
