Chemical Structure
Description
The occurrence of Flurbiprofen impurity 30 is closely related to a salt form, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Flurbiprofen impurity 30 (CAS 56985-74-1) is a high-purity analytical reference standard with the molecular formula C3H5BrO2Na and a molecular weight of 175.97 g/mol.
Flurbiprofen impurity 30 (C3H5BrO2Na) contains a salt form, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
