Chemical Structure
Description
The occurrence of 5-Hydroxy-1,3-dimethylindolin-2-one 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-Hydroxy-1,3-dimethylindolin-2-one (CAS 1010-68-0), molecular formula C10H11NO2 and molecular weight 177.20 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 5-Hydroxy-1,3-dimethylindolin-2-one (C10H11NO2) 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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-Hydroxy-1,3-dimethylindolin-2-one 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.
