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-Bis(bromomethyl)-2-methoxy-5-(octyloxy)benzene (CAS 151835-56-2) is a high-purity analytical reference standard with the molecular formula C17H26Br2O2 and a molecular weight of 422.20 g/mol.
The molecular framework of 1,4-Bis(bromomethyl)-2-methoxy-5-(octyloxy)benzene (C17H26Br2O2) 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. 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).
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.
