Chemical Structure
Description
Based on its molecular formula C9H14N4O3C2HF3O2, D-Carnosine TFA salt contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 340.26 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.
D-Carnosine TFA salt (CAS 5853-00-9(Free Base)) is a high-purity analytical reference standard with the molecular formula C9H14N4O3C2HF3O2 and a molecular weight of 340.26 g/mol.
