Chemical Structure
Description
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.
rac 1-[3,4-(Dibenzyloxy)phenyl]-2-bromo-1-butanone (CAS 24538-60-1) is a high-purity analytical reference standard with the molecular formula C24H23BrO3 and a molecular weight of 439.34 g/mol.
The molecular framework of rac 1-[3,4-(Dibenzyloxy)phenyl]-2-bromo-1-butanone (C24H23BrO3) is characterized by a steroid core, a hydroxyl group, an ether linkage, bromine 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
