Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 417.93 g/mol gives Ethyl 3,3-diethoxy-2-methylpropanoate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Ethyl 3,3-diethoxy-2-methylpropanoate (CAS 36056-90-3) is a high-purity analytical reference standard with the molecular formula C18H21ClN2C4H7NO3 and a molecular weight of 417.93 g/mol.
Based on its molecular formula C18H21ClN2C4H7NO3, Ethyl 3,3-diethoxy-2-methylpropanoate contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 417.93 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
