(5S,6R,7E,9E,11Z,13E,15S,17Z)-5,6,15-Trihydroxyicosa-7,9,11,13,17-pentaenoic acid CAS 110657-98-2 chemical structure

Description

The occurrence of (5S,6R,7E,9E,11Z,13E,15S,17Z)-5,6,15-Trihydroxyicosa-7,9,11,13,17-pentaenoic acid is closely related to a steroid core, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies (5S,6R,7E,9E,11Z,13E,15S,17Z)-5,6,15-Trihydroxyicosa-7,9,11,13,17-pentaenoic acid (CAS 110657-98-2), a certified reference material (molecular formula C20H30O5, MW 350.45 g/mol) for analytical method development and quality control.

Structurally, (5S,6R,7E,9E,11Z,13E,15S,17Z)-5,6,15-Trihydroxyicosa-7,9,11,13,17-pentaenoic acid (C20H30O5) contains a steroid core, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 350.45 g/mol, it falls into the moderately-high-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
