Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5-(2-Chloro-5-nitrophenyl)-3-(3,4-dimethylphenyl)-1,2,4-oxadiazole.
5-(2-Chloro-5-nitrophenyl)-3-(3,4-dimethylphenyl)-1,2,4-oxadiazole (CAS 1710202-15-5) is a high-purity analytical reference standard with the molecular formula C16H12ClN3O3 and a molecular weight of 329.74 g/mol.
The molecular framework of 5-(2-Chloro-5-nitrophenyl)-3-(3,4-dimethylphenyl)-1,2,4-oxadiazole (C16H12ClN3O3) 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 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.
As a certified reference material (CRM), 5-(2-Chloro-5-nitrophenyl)-3-(3,4-dimethylphenyl)-1,2,4-oxadiazole 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.
