Chemical Structure

beta-Butyrolactone CAS 3068-88-0 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 86.09 g/mol gives beta-Butyrolactone distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

beta-Butyrolactone (CAS 3068-88-0) is a high-purity analytical reference standard with the molecular formula C4H6O2 and a molecular weight of 86.09 g/mol.

Based on its molecular formula C4H6O2, beta-Butyrolactone 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 86.09 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.
