4-Amino-2-(3-methyl-2,6-dioxopiperidin-3-yl)isoindoline-1,3-dione (CAS 202271-87-2), molecular formula C14H13N3O4 and molecular weight 287.27 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 4-Amino-2-(3-methyl-2,6-dioxopiperidin-3-yl)isoindoline-1,3-dione (C14H13N3O4) is characterized by a nitrogen-containing heterocyclic scaffold, 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
