Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-((5-(2-Bromophenyl)-1,3,4-oxadiazol-2-yl)thio)-N-(3,5-dichlorophenyl)acetamide.
2-((5-(2-Bromophenyl)-1,3,4-oxadiazol-2-yl)thio)-N-(3,5-dichlorophenyl)acetamide (CAS 334503-65-0) is a high-purity analytical reference standard with the molecular formula C16H10BrCl2N3O2S and a molecular weight of 459.14 g/mol.
The molecular framework of 2-((5-(2-Bromophenyl)-1,3,4-oxadiazol-2-yl)thio)-N-(3,5-dichlorophenyl)acetamide (C16H10BrCl2N3O2S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine/bromine 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
As a certified reference material (CRM), 2-((5-(2-Bromophenyl)-1,3,4-oxadiazol-2-yl)thio)-N-(3,5-dichlorophenyl)acetamide 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.
