Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 232.32 g/mol gives 3-(Diethoxymethyl)-2-ethoxytetrahydro-2H-pyran distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
3-(Diethoxymethyl)-2-ethoxytetrahydro-2H-pyran (CAS 69549-51-5) is a high-purity analytical reference standard with the molecular formula C12H24O4 and a molecular weight of 232.32 g/mol.
Based on its molecular formula C12H24O4, 3-(Diethoxymethyl)-2-ethoxytetrahydro-2H-pyran 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 232.32 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.
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.
