Chemical Structure
Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
(E)-2-Acetoxy-2-bromo-5-chlorostilbene (CAS 1000890-01-6) is a high-purity analytical reference standard with the molecular formula C16H12BrClO2 and a molecular weight of 351.62 g/mol.
The molecular framework of (E)-2-Acetoxy-2-bromo-5-chlorostilbene (C16H12BrClO2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine/bromine substitution, a polycyclic aromatic 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
CATO manufactures (E)-2-Acetoxy-2-bromo-5-chlorostilbene under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
