2-Methylbutanoic anhydride CAS 1519-23-9

Description

The occurrence of 2-Methylbutanoic anhydride is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

2-Methylbutanoic anhydride (CAS 1519-23-9) is a high-purity analytical reference standard with the molecular formula C10H18O3 and a molecular weight of 186.25 g/mol.

Based on its molecular formula C10H18O3, 2-Methylbutanoic anhydride contains a carboxylic acid group, a hydroxyl group, an ether linkage; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 186.25 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
