Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 138.99 g/mol gives 2-Bromo-1-propanol distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2-Bromo-1-propanol (CAS 598-18-5) is a high-purity analytical reference standard with the molecular formula C3H7BrO and a molecular weight of 138.99 g/mol.
Based on its molecular formula C3H7BrO, 2-Bromo-1-propanol contains a hydroxyl group, an ether linkage, bromine substitution; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 138.99 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
