Chemical Structure

cis-2,3-epoxybutane CAS 1758-33-4 chemical structure

Description

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.

cis-2,3-epoxybutane (CAS 1758-33-4), molecular formula C4H8O and molecular weight 72.11 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C4H8O, cis-2,3-epoxybutane contains a hydroxyl group, an ether linkage; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 72.11 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry.

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.
