Chemical Structure
Description
1,3-Dihydro-1,3-dioxo-2H-isoindol-2-yl 2-ethylhexanoate (CAS 1872262-63-9), molecular formula C16H19NO4 and molecular weight 289.33 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1,3-Dihydro-1,3-dioxo-2H-isoindol-2-yl 2-ethylhexanoate (C16H19NO4) 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
