Chemical Structure
Description
The occurrence of 3,5-dimethylpyrrolidin-2-one is closely related to an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
3,5-dimethylpyrrolidin-2-one (CAS 18591-83-8) is a high-purity analytical reference standard with the molecular formula C6H11NO and a molecular weight of 113.16 g/mol.
Based on its molecular formula C6H11NO, 3,5-dimethylpyrrolidin-2-one contains an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 113.16 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
