Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
1-(3,5-Dichlorophenyl)-3,3-dimethylazetidin-2-one (CAS 478261-96-0) is a high-purity analytical reference standard with the molecular formula C11H11Cl2NO and a molecular weight of 244.12 g/mol.
The molecular framework of 1-(3,5-Dichlorophenyl)-3,3-dimethylazetidin-2-one (C11H11Cl2NO) 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.
As a certified reference material (CRM), 1-(3,5-Dichlorophenyl)-3,3-dimethylazetidin-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.
