Chemical Structure
Description
5-(4-Amino-3-bromophenyl)-1,3,4-oxadiazole-2-thiol (CAS 887584-46-5), molecular formula C8H6BrN3OS and molecular weight 272.12 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 5-(4-Amino-3-bromophenyl)-1,3,4-oxadiazole-2-thiol (C8H6BrN3OS) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, 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. 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-(4-Amino-3-bromophenyl)-1,3,4-oxadiazole-2-thiol 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.
