Chemical Structure
Description
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.
CATO supplies (5Z,8S,9E,11E,13E,15S)-8,15-Dihydroxyicosa-5,9,11,13-tetraenoic acid (CAS 80234-66-8), a certified reference material (molecular formula C20H32O4, MW 336.47 g/mol) for analytical method development and quality control.
Structurally, (5Z,8S,9E,11E,13E,15S)-8,15-Dihydroxyicosa-5,9,11,13-tetraenoic acid (C20H32O4) contains a steroid core, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 336.47 g/mol, it falls into the moderately-high-molecular-weight range. 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.
