Chemical Structure
Description
The occurrence of rel-(1R,2S)-2-Bromocyclopropane-1-carboxylic acid is closely related to 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.
rel-(1R,2S)-2-Bromocyclopropane-1-carboxylic acid (CAS 60212-40-0) is a high-purity analytical reference standard with the molecular formula C4H5BrO2 and a molecular weight of 164.99 g/mol.
rel-(1R,2S)-2-Bromocyclopropane-1-carboxylic acid (C4H5BrO2) contains 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.
