Description
As a certified reference material (CRM), 1-(3,5-Dichlorophenyl)-2,6-dimethyl-4,5,6,7-tetrahydro-1H-indol-4-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.
1-(3,5-Dichlorophenyl)-2,6-dimethyl-4,5,6,7-tetrahydro-1H-indol-4-one (CAS 1022480-78-9), molecular formula C16H15Cl2NO and molecular weight 308.20 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, 1-(3,5-Dichlorophenyl)-2,6-dimethyl-4,5,6,7-tetrahydro-1H-indol-4-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 308.20 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
