Chemical Structure
Description
The occurrence of Ethyl 8-(3-bromo-4-methylphenyl)-8-oxooctanoate is closely related to a steroid core, a hydroxyl group, an ether linkage, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Ethyl 8-(3-bromo-4-methylphenyl)-8-oxooctanoate (CAS 898776-90-4) is a high-purity analytical reference standard with the molecular formula C17H23BrO3 and a molecular weight of 355.27 g/mol.
Owing to a steroid core, a hydroxyl group, an ether linkage, bromine substitution, Ethyl 8-(3-bromo-4-methylphenyl)-8-oxooctanoate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 355.27 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
