Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
1,4-Dichloro-2-(3-chlorobut-3-en-1-yl)benzene (CAS 951892-76-5) is a high-purity analytical reference standard with the molecular formula C10H9Cl3 and a molecular weight of 235.54 g/mol.
The molecular framework of 1,4-Dichloro-2-(3-chlorobut-3-en-1-yl)benzene (C10H9Cl3) is characterized by chlorine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
As a certified reference material (CRM), 1,4-Dichloro-2-(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.
