3-[5-[3-(3-hydroxypropoxy)prop-1-ynyl]-1-oxo-isoindolin-2-yl]piperidine-2,6-dione CAS 2767218-83-5

Description

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.

3-[5-[3-(3-hydroxypropoxy)prop-1-ynyl]-1-oxo-isoindolin-2-yl]piperidine-2,6-dione (CAS 2767218-83-5), molecular formula C19H20N2O5 and molecular weight 356.37 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 3-[5-[3-(3-hydroxypropoxy)prop-1-ynyl]-1-oxo-isoindolin-2-yl]piperidine-2,6-dione (C19H20N2O5) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
