α-Linolenic acid CAS 463-40-1

Description

Compared with other compounds in its class, the molecular weight of 278.43 g/mol gives α-Linolenic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

α-Linolenic acid (CAS 463-40-1), molecular formula C18H30O2 and molecular weight 278.43 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of α-Linolenic acid (C18H30O2) 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 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.
