Description
822-17-3 872C9A1W9I Sodium linoleate 9,12-Octadecadienoic acid (Z,Z)-, sodium salt Sodium (9Z,12Z)-octadeca-9,12-dienoate 9,12-Octadecadienoic acid (9Z,12Z)-, sodium salt (1:1) 9,12-Octadecadienoic acid (9Z,12Z)-, sodium salt EINECS 212-491-0 Linoleic acid, sodium salt UNII-872C9A1W9I 9,12-Octadecadienoic acid (9Z, 12Z)-, sodium salt (CAS 822-17-3) is a high-purity analytical reference standard with the molecular formula C18H31O2Na and a molecular weight of 302.43 g/mol.
The molecular framework of 822-17-3 872C9A1W9I Sodium linoleate 9,12-Octadecadienoic acid (Z,Z)-, sodium salt Sodium (9Z,12Z)-octadeca-9,12-dienoate 9,12-Octadecadienoic acid (9Z,12Z)-, sodium salt (1:1) 9,12-Octadecadienoic acid (9Z,12Z)-, sodium salt EINECS 212-491-0 Linoleic acid, sodium salt UNII-872C9A1W9I 9,12-Octadecadienoic acid (9Z, 12Z)-, sodium salt (C18H31O2Na) is characterized by a carboxylic acid group, 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).
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.
