Chemical Structure

N-propylsulfoxide CAS 4253-91-2 chemical structure

Description

The occurrence of N-propylsulfoxide is closely related to sulfur-containing functionality, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

N-propylsulfoxide (CAS 4253-91-2), molecular formula C6H14OS and molecular weight 134.24 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C6H14OS, N-propylsulfoxide contains sulfur-containing functionality, a hydroxyl group, an ether linkage; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 134.24 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry.

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.
