(8Z,11Z,14Z)-Icosa-8,11,14-trien-5-ynoic acid CAS 58688-54-3 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (8Z,11Z,14Z)-Icosa-8,11,14-trien-5-ynoic acid.

CATO supplies (8Z,11Z,14Z)-Icosa-8,11,14-trien-5-ynoic acid (CAS 58688-54-3), a certified reference material (molecular formula C20H30O2, MW 302.45 g/mol) for analytical method development and quality control.

The molecular framework of (8Z,11Z,14Z)-Icosa-8,11,14-trien-5-ynoic acid (C20H30O2) 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 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.

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.
