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 Ethyl 5-amino-4-bromo-2-fluorobenzoate.
Ethyl 5-amino-4-bromo-2-fluorobenzoate (CAS 1339673-69-6), molecular formula C9H9BrFNO2 and molecular weight 262.08 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C9H9BrFNO2, Ethyl 5-amino-4-bromo-2-fluorobenzoate contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 262.08 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.
