Chemical Structure
Description
The occurrence of Ethyl 6-amino-5-cyano-2-[({3-cyano-5H,6H,7H,8H,9H-cyclohepta[b]pyridin-2-yl}sulfanyl)methyl]-4-(3,4-dichlorophenyl)-4H-pyran-3-carboxylate is closely related to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Ethyl 6-amino-5-cyano-2-[({3-cyano-5H,6H,7H,8H,9H-cyclohepta[b]pyridin-2-yl}sulfanyl)methyl]-4-(3,4-dichlorophenyl)-4H-pyran-3-carboxylate (CAS 445384-07-6) is a high-purity analytical reference standard with the molecular formula C27H24Cl2N4O3S and a molecular weight of 555.48 g/mol.
Ethyl 6-amino-5-cyano-2-[({3-cyano-5H,6H,7H,8H,9H-cyclohepta[b]pyridin-2-yl}sulfanyl)methyl]-4-(3,4-dichlorophenyl)-4H-pyran-3-carboxylate (C27H24Cl2N4O3S) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
