Chemical Structure
Description
As a certified reference material (CRM), Methanone, (5-bromo-2-fluorophenyl)-2-thienyl- 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.
Methanone, (5-bromo-2-fluorophenyl)-2-thienyl- (CAS 1094251-95-2), molecular formula C11H6BrFOS and molecular weight 285.13 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C11H6BrFOS, Methanone, (5-bromo-2-fluorophenyl)-2-thienyl- contains sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine/bromine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 285.13 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
