Chemical Structure
Description
Based on its molecular formula C9H9ClFNO2, Ethyl 2-amino-3-chloro-5-fluorobenzoate contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 217.62 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Ethyl 2-amino-3-chloro-5-fluorobenzoate (CAS 1179055-07-2), molecular formula C9H9ClFNO2 and molecular weight 217.62 g/mol, is a CATO reference standard with documented purity and traceability.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
