Chemical Structure
Description
The occurrence of 5-Bromoquinoline-8-carbonitrile hydrochloride is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine/bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
5-Bromoquinoline-8-carbonitrile hydrochloride (CAS 2155855-06-2), molecular formula C10H5BrN2HCl and molecular weight 269.53 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C10H5BrN2HCl, 5-Bromoquinoline-8-carbonitrile hydrochloride contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine/bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 269.53 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
As a certified reference material (CRM), 5-Bromoquinoline-8-carbonitrile hydrochloride meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
