5-(Pentafluorosulfanyl)-1,3-dihydro-2H-benzimidazole-2-thione CAS 1211526-90-7

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5-(Pentafluorosulfanyl)-1,3-dihydro-2H-benzimidazole-2-thione.

5-(Pentafluorosulfanyl)-1,3-dihydro-2H-benzimidazole-2-thione (CAS 1211526-90-7), molecular formula C7H5F5N2S2 and molecular weight 276.25 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 5-(Pentafluorosulfanyl)-1,3-dihydro-2H-benzimidazole-2-thione (C7H5F5N2S2) is characterized by a nitrile group, sulfur-containing functionality, fluorine substitution, an aromatic ring system. 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
