Chemical Structure
Description
Structurally, 2-Diethoxyphosphoryl-2-phenethyl-pyrrolidine 434941-00-1 Diethyl (2-Phenethyl-pyrrolidin-2-yl)phosphonate [2-(2-Phenylethyl)-2-pyrrolidinyl]phosphonic Acid Diethyl Ester (C16H26NO3P) contains a nitrogen-containing heterocyclic scaffold, an amide group, a phosphonate group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 4.5, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 311.36 g/mol, it falls into the moderately-high-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
CATO supplies 2-Diethoxyphosphoryl-2-phenethyl-pyrrolidine 434941-00-1 Diethyl (2-Phenethyl-pyrrolidin-2-yl)phosphonate [2-(2-Phenylethyl)-2-pyrrolidinyl]phosphonic Acid Diethyl Ester (CAS 434941-00-1), a certified reference material (molecular formula C16H26NO3P, MW 311.36 g/mol) for analytical method development and quality control.
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.
