Chemical Structure
Description
1-Phenyl-7-(pyridin-3-yl)-5-(trifluoromethyl)-1H-benzo[d]imidazole (CAS 159725-99-2) is a high-purity analytical reference standard with the molecular formula C19H12F3N3 and a molecular weight of 339.31 g/mol.
Structurally, 1-Phenyl-7-(pyridin-3-yl)-5-(trifluoromethyl)-1H-benzo[d]imidazole (C19H12F3N3) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 14.0, corresponding to approximately 14 ring(s) or double-bond equivalent(s). With a molecular weight of 339.31 g/mol, it falls into the moderately-high-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
CATO manufactures 1-Phenyl-7-(pyridin-3-yl)-5-(trifluoromethyl)-1H-benzo[d]imidazole under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
