Chemical Structure

Di-n-octyl sulfoxide CAS 1986-89-6 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.

Di-n-octyl sulfoxide (CAS 1986-89-6), molecular formula C16H34OS and molecular weight 274.51 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of Di-n-octyl sulfoxide (C16H34OS) is characterized by sulfur-containing functionality, 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.
