Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Methyl 5-chloroquinoline-8-carboxylate.
Methyl 5-chloroquinoline-8-carboxylate (CAS 16220-22-7) is a high-purity analytical reference standard with the molecular formula C11H8ClNO2 and a molecular weight of 221.64 g/mol.
Based on its molecular formula C11H8ClNO2, Methyl 5-chloroquinoline-8-carboxylate 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 221.64 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).
