Chemical Structure
Description
The molecular framework of 2-Chloro-4-(4-ethoxyphenyl)-1-butene (C12H15ClO) is characterized by a hydroxyl group, an ether linkage, 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
2-Chloro-4-(4-ethoxyphenyl)-1-butene (CAS 951889-92-2) is a high-purity analytical reference standard with the molecular formula C12H15ClO and a molecular weight of 210.70 g/mol.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
