The occurrence of 3-[4-[3-(2-methoxyethoxy)prop-1-ynyl]-1-oxo-isoindolin-2-yl]piperidine-2,6-dione is closely related to a flavonoid core, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 3-[4-[3-(2-methoxyethoxy)prop-1-ynyl]-1-oxo-isoindolin-2-yl]piperidine-2,6-dione (CAS 2408797-39-5), a certified reference material (molecular formula C19H20N2O5, MW 356.37 g/mol) for analytical method development and quality control.
3-[4-[3-(2-methoxyethoxy)prop-1-ynyl]-1-oxo-isoindolin-2-yl]piperidine-2,6-dione (C19H20N2O5) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
