Chemical Structure
Description
The occurrence of Methyl 6-amino-5-cyano-2-(((3-cyano-4,6-dimethylpyridin-2-yl)thio)methyl)-4-(pyridin-3-yl)-4H-pyran-3-carboxylate is closely related to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Methyl 6-amino-5-cyano-2-(((3-cyano-4,6-dimethylpyridin-2-yl)thio)methyl)-4-(pyridin-3-yl)-4H-pyran-3-carboxylate (CAS 354554-90-8) is a high-purity analytical reference standard with the molecular formula C22H19N5O3S and a molecular weight of 433.48 g/mol.
The molecular framework of Methyl 6-amino-5-cyano-2-(((3-cyano-4,6-dimethylpyridin-2-yl)thio)methyl)-4-(pyridin-3-yl)-4H-pyran-3-carboxylate (C22H19N5O3S) is characterized by a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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).
