2-Bromo-6-octyl-3,4-dihydronaphthalen-1(2H)-one CAS 945632-77-9

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.

2-Bromo-6-octyl-3,4-dihydronaphthalen-1(2H)-one (CAS 945632-77-9) is a high-purity analytical reference standard with the molecular formula C18H25BrO and a molecular weight of 337.29 g/mol.

Based on its molecular formula C18H25BrO, 2-Bromo-6-octyl-3,4-dihydronaphthalen-1(2H)-one contains a steroid core, a hydroxyl group, an ether linkage, bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 337.29 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
