Chemical Structure

5-Bromopentan-2-ol CAS 62957-46-4 chemical structure

Description

5-Bromopentan-2-ol (CAS 62957-46-4) is a high-purity analytical reference standard with the molecular formula C5H11BrO and a molecular weight of 167.04 g/mol.

The molecular framework of 5-Bromopentan-2-ol (C5H11BrO) is characterized by a hydroxyl group, an ether linkage, bromine substitution. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.

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.
