Chemical Structure
Description
The occurrence of 1-(4-Bromophenyl)but-3-yn-1-ol is closely related to a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
1-(4-Bromophenyl)but-3-yn-1-ol (CAS 94612-95-0) is a high-purity analytical reference standard with the molecular formula C10H9BrO and a molecular weight of 225.08 g/mol.
Based on its molecular formula C10H9BrO, 1-(4-Bromophenyl)but-3-yn-1-ol contains a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 225.08 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
