Chemical Structure
Description
(5-(Dimethoxymethyl)pyridin-2-yl)dimethylphosphine oxide (CAS 2648962-76-7) is a high-purity analytical reference standard with the molecular formula C10H16NO3P and a molecular weight of 229.21 g/mol.
(5-(Dimethoxymethyl)pyridin-2-yl)dimethylphosphine oxide (C10H16NO3P) contains an amide group, a phosphonate group, a carboxylic acid group, a hydroxyl group, an ether linkage. It is notably hygroscopic, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
