Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 237.09 g/mol gives (5-Bromo-1-naphthyl)methanol distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
(5-Bromo-1-naphthyl)methanol (CAS 20366-57-8) is a high-purity analytical reference standard with the molecular formula C11H9BrO and a molecular weight of 237.09 g/mol.
Structurally, (5-Bromo-1-naphthyl)methanol (C11H9BrO) contains a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 237.09 g/mol, it falls into the medium-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
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.
