Chemical Structure
Description
4-hydroxy-2,3-dihydro-1H-isoindole-1,3-dione (CAS 41709-87-9) is a high-purity analytical reference standard with the molecular formula C8H5NO3 and a molecular weight of 163.13 g/mol.
The molecular framework of 4-hydroxy-2,3-dihydro-1H-isoindole-1,3-dione (C8H5NO3) 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 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.
As a certified reference material (CRM), 4-hydroxy-2,3-dihydro-1H-isoindole-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.
