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 4-(3-Bromophenyl)-1,3-dihydro-2H-imidazole-2-thione.
4-(3-Bromophenyl)-1,3-dihydro-2H-imidazole-2-thione (CAS 192800-59-2) is a high-purity analytical reference standard with the molecular formula C9H7BrN2S and a molecular weight of 255.13 g/mol.
The molecular framework of 4-(3-Bromophenyl)-1,3-dihydro-2H-imidazole-2-thione (C9H7BrN2S) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, 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), 4-(3-Bromophenyl)-1,3-dihydro-2H-imidazole-2-thione 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.
