Chemical Structure
Description
1-Bromo-3-(3-chlorobut-3-en-1-yl)benzene (CAS 485320-30-7), molecular formula C10H10BrCl and molecular weight 245.54 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 1-Bromo-3-(3-chlorobut-3-en-1-yl)benzene (C10H10BrCl) contains chlorine/bromine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 245.54 g/mol, it falls into the medium-molecular-weight range. 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), 1-Bromo-3-(3-chlorobut-3-en-1-yl)benzene 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.
