Chemical Structure
Description
The occurrence of Methyl (R)-4-bromo-2-hydroxybutanoate is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies Methyl (R)-4-bromo-2-hydroxybutanoate (CAS 193827-67-7), a certified reference material (molecular formula C5H9BrO3, MW 197.03 g/mol) for analytical method development and quality control.
Based on its molecular formula C5H9BrO3, Methyl (R)-4-bromo-2-hydroxybutanoate contains a carboxylic acid group, 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 197.03 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.
