Chemical Structure
Description
Based on its molecular formula C12H15BrO2, tert-Butyl 3-bromo-4-methylbenzoate contains a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 271.15 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.
CATO supplies tert-Butyl 3-bromo-4-methylbenzoate (CAS 160952-57-8), a certified reference material (molecular formula C12H15BrO2, MW 271.15 g/mol) for analytical method development and quality control.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
