CATO supplies 13(S)-Hydroperoxy-9(Z),11(E),15(Z)-octadecatrienoic acid 13(S)-Hydroperoxylinolenic acid 13-(S)-Hydroperoxylinolenic acid 67597-26-6 9,11,15-Octadecatrienoic acid, 13-hydroperoxy-, [S-(E,Z,Z)]- 9,11,15-octadecatrienoic acid, 13-hydroperoxy-, (9Z,11E,13S,15Z)- CMC_7377 (CAS 67597-26-6), a certified reference material (molecular formula C18H30O4, MW 310.43 g/mol) for analytical method development and quality control.
The molecular framework of 13(S)-Hydroperoxy-9(Z),11(E),15(Z)-octadecatrienoic acid 13(S)-Hydroperoxylinolenic acid 13-(S)-Hydroperoxylinolenic acid 67597-26-6 9,11,15-Octadecatrienoic acid, 13-hydroperoxy-, [S-(E,Z,Z)]- 9,11,15-octadecatrienoic acid, 13-hydroperoxy-, (9Z,11E,13S,15Z)- CMC_7377 (C18H30O4) 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
