Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 486.95 g/mol gives 4,5-Dibromo-N-(3-iodophenyl)thiophene-2-carboxamide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 4,5-Dibromo-N-(3-iodophenyl)thiophene-2-carboxamide (CAS 749893-00-3), a certified reference material (molecular formula C11H6Br2INOS, MW 486.95 g/mol) for analytical method development and quality control.
The molecular framework of 4,5-Dibromo-N-(3-iodophenyl)thiophene-2-carboxamide (C11H6Br2INOS) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, bromine/iodine 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.
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), 4,5-Dibromo-N-(3-iodophenyl)thiophene-2-carboxamide 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.
