Chemical Structure
Description
The occurrence of SM-21 maleate is closely related to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
SM-21 maleate (CAS 155058-71-2), molecular formula C18H24ClNO3C4H4O4 and molecular weight 453.92 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C18H24ClNO3C4H4O4, SM-21 maleate contains a flavonoid core, 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 453.92 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
