Chemical Structure
Description
The occurrence of 4-Bromo-2-fluoroaniline sulfate is closely related to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
4-Bromo-2-fluoroaniline sulfate (CAS 1951441-95-4), molecular formula C6H5BrFNH2O4S and molecular weight 288.09 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 4-Bromo-2-fluoroaniline sulfate (C6H5BrFNH2O4S) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 288.09 g/mol, it falls into the medium-molecular-weight range. 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.
