Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Diethyl ((1R)-quinolin-4-yl(5-vinylquinuclidin-2-yl)methyl)phosphoramidate.
Diethyl ((1R)-quinolin-4-yl(5-vinylquinuclidin-2-yl)methyl)phosphoramidate (CAS 1354565-16-4) is a high-purity analytical reference standard with the molecular formula C23H32N3O3P and a molecular weight of 429.49 g/mol.
Owing to a steroid core, an amide group, a phosphonate group, a hydroxyl group, an ether linkage, Diethyl ((1R)-quinolin-4-yl(5-vinylquinuclidin-2-yl)methyl)phosphoramidate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 429.49 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
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.
