Chemical Structure
Description
The occurrence of 4-(5-Bromopyridin-2-yl)-2-methylbut-3-yn-2-ol is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
4-(5-Bromopyridin-2-yl)-2-methylbut-3-yn-2-ol (CAS 134321-95-2), molecular formula C10H10BrNO and molecular weight 240.10 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C10H10BrNO, 4-(5-Bromopyridin-2-yl)-2-methylbut-3-yn-2-ol contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 240.10 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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).
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.
