2-(4-Chlorophenyl)-6-(pentafluoro-λ6-sulfanyl)-1H-benzo[d]imidazole CAS 1379803-56-1

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-(4-Chlorophenyl)-6-(pentafluoro-λ6-sulfanyl)-1H-benzo[d]imidazole.

2-(4-Chlorophenyl)-6-(pentafluoro-λ6-sulfanyl)-1H-benzo[d]imidazole (CAS 1379803-56-1), molecular formula C13H8ClF5N2S and molecular weight 354.73 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 2-(4-Chlorophenyl)-6-(pentafluoro-λ6-sulfanyl)-1H-benzo[d]imidazole (C13H8ClF5N2S) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, fluorine/chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 354.73 g/mol, it falls into the moderately-high-molecular-weight range. 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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
