Chemical Structure
Description
1-Chloro-4-[4-Chloro-1-(4-Fluorophenyl)-1-Butenyl]Benzene (CAS 83929-31-1) is a high-purity analytical reference standard with the molecular formula C16H13Cl2F and a molecular weight of 295.18 g/mol.
Based on its molecular formula C16H13Cl2F, 1-Chloro-4-[4-Chloro-1-(4-Fluorophenyl)-1-Butenyl]Benzene contains fluorine/chlorine substitution, a polycyclic aromatic system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 295.18 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 1-Chloro-4-[4-Chloro-1-(4-Fluorophenyl)-1-Butenyl]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.
