Chemical Structure
Description
Based on its molecular formula C11H12O4, 5-[(oxiran-2-ylmethoxy)methyl]-1,3-dioxaindane contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 208.21 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.
5-[(oxiran-2-ylmethoxy)methyl]-1,3-dioxaindane (CAS 157134-90-2) is a high-purity analytical reference standard with the molecular formula C11H12O4 and a molecular weight of 208.21 g/mol.
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.
