Chemical Structure
Description
The occurrence of 2-Chloro-5-cyclopropoxynicotinic acid is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2-Chloro-5-cyclopropoxynicotinic acid (CAS 1243409-31-5) is a high-purity analytical reference standard with the molecular formula C9H8ClNO3 and a molecular weight of 213.62 g/mol.
Based on its molecular formula C9H8ClNO3, 2-Chloro-5-cyclopropoxynicotinic acid contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 213.62 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).
