Chemical Structure
Description
Owing to a nitrile group, chlorine substitution, 4887-82-5 6-Chloro-1H-Benzimidazole 6-chloro-1H-benzo[d]imidazole A18809 is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 160.64 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
4887-82-5 6-Chloro-1H-Benzimidazole 6-chloro-1H-benzo[d]imidazole A18809 (CAS 4887-82-5), molecular formula C7H13ClN2 and molecular weight 160.64 g/mol, is a CATO reference standard with documented purity and traceability.
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.
