Chemical Structure

6,9,12,15,18-Heneicosapentayn-1-ol CAS 84456-77-9 chemical structure

Description

The molecular framework of 6,9,12,15,18-Heneicosapentayn-1-ol (C21H24O) is characterized by a steroid core, 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).

6,9,12,15,18-Heneicosapentayn-1-ol (CAS 84456-77-9) is a high-purity analytical reference standard with the molecular formula C21H24O and a molecular weight of 292.41 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.

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.
