Chemical Structure
Description
4-Fluoro-1H-benzimidazole (CAS 5847-89-2), molecular formula C7H5FN2 and molecular weight 136.13 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 4-Fluoro-1H-benzimidazole (C7H5FN2) contains a nitrile group, fluorine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 136.13 g/mol, it falls into the low-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
