Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-bromo-3-methylbutanoic acid.
3-bromo-3-methylbutanoic acid (CAS 5798-88-9) is a high-purity analytical reference standard with the molecular formula C5H9BrO2 and a molecular weight of 181.03 g/mol.
Based on its molecular formula C5H9BrO2, 3-bromo-3-methylbutanoic acid 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 181.03 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.
