Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
5-[1-[4-(2-Chloroethoxy)phenyl]-2-phenyl-1-buten-1-yl]-1,3-benzodioxole (E/Z Mixture) (CAS 259149-68-3), molecular formula C25H23ClO3 and molecular weight 406.90 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 5-[1-[4-(2-Chloroethoxy)phenyl]-2-phenyl-1-buten-1-yl]-1,3-benzodioxole (E/Z Mixture) (C25H23ClO3) is characterized by a steroid core, a hydroxyl group, an ether linkage, chlorine substitution. 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.
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.
