Chemical Structure

5-Amino-2-ethylisoindoline-1,3-dione CAS 55080-55-2 chemical structure

Description

The occurrence of 5-Amino-2-ethylisoindoline-1,3-dione is closely related to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

5-Amino-2-ethylisoindoline-1,3-dione (CAS 55080-55-2), molecular formula C10H10N2O2 and molecular weight 190.20 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 5-Amino-2-ethylisoindoline-1,3-dione (C10H10N2O2) is characterized by an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

As a certified reference material (CRM), 5-Amino-2-ethylisoindoline-1,3-dione meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
