1-(4-Fluorophenyl)-5-nitro-1h-benzo[d]imidazole-2-thiol CAS 731003-61-5

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-(4-Fluorophenyl)-5-nitro-1h-benzo[d]imidazole-2-thiol.

1-(4-Fluorophenyl)-5-nitro-1h-benzo[d]imidazole-2-thiol (CAS 731003-61-5), molecular formula C13H8FN3O2S and molecular weight 289.28 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 1-(4-Fluorophenyl)-5-nitro-1h-benzo[d]imidazole-2-thiol (C13H8FN3O2S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine 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.

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), 1-(4-Fluorophenyl)-5-nitro-1h-benzo[d]imidazole-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.
