Chemical Structure
Description
The occurrence of 2-(3-Chlorophenyl)isoindoline-1,3-dione is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2-(3-Chlorophenyl)isoindoline-1,3-dione (CAS 16082-71-6), molecular formula C14H8ClNO2 and molecular weight 257.67 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-(3-Chlorophenyl)isoindoline-1,3-dione (C14H8ClNO2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. 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 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.
As a certified reference material (CRM), 2-(3-Chlorophenyl)isoindoline-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.
