Chemical Structure
Description
The molecular framework of 5-Chloro-3,3-dimethyl-2,3-dihydro-1h-indol-2-one (C10H10ClNO) 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
5-Chloro-3,3-dimethyl-2,3-dihydro-1h-indol-2-one (CAS 74492-46-9), molecular formula C10H10ClNO and molecular weight 195.65 g/mol, is a CATO reference standard with documented purity and traceability.
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-Chloro-3,3-dimethyl-2,3-dihydro-1h-indol-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.
