2,2'-(1-Hydroxyethane-1,2-diyl)diisoindoline-1,3-dione CAS 1415562-69-4

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2,2'-(1-Hydroxyethane-1,2-diyl)diisoindoline-1,3-dione.

2,2'-(1-Hydroxyethane-1,2-diyl)diisoindoline-1,3-dione (CAS 1415562-69-4), molecular formula C18H12N2O5 and molecular weight 336.30 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 2,2'-(1-Hydroxyethane-1,2-diyl)diisoindoline-1,3-dione (C18H12N2O5) 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. 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.
