Chemical Structure
Description
CATO supplies 2-(3-Bromobut-3-en-1-yl)-1-chloro-3-fluorobenzene (CAS 951895-17-3), a certified reference material (molecular formula C10H9BrClF, MW 263.53 g/mol) for analytical method development and quality control.
Based on its molecular formula C10H9BrClF, 2-(3-Bromobut-3-en-1-yl)-1-chloro-3-fluorobenzene contains fluorine/chlorine/bromine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 263.53 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.
As a certified reference material (CRM), 2-(3-Bromobut-3-en-1-yl)-1-chloro-3-fluorobenzene 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.
