Description
As a certified reference material (CRM), 2-(4-(4-Chlorophenyl)-2-methyl-3-oxo-1,2,4-oxadiazolidin-5-yl)-N-cycloheptylacetamide 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.
2-(4-(4-Chlorophenyl)-2-methyl-3-oxo-1,2,4-oxadiazolidin-5-yl)-N-cycloheptylacetamide (CAS 672949-07-4) is a high-purity analytical reference standard with the molecular formula C18H24ClN3O3 and a molecular weight of 365.85 g/mol.
The molecular framework of 2-(4-(4-Chlorophenyl)-2-methyl-3-oxo-1,2,4-oxadiazolidin-5-yl)-N-cycloheptylacetamide (C18H24ClN3O3) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
