Chemical Structure
Description
OTSSP167 hydrochloride (C25H28Cl2N4O2HCl) contains a steroid core, an amide 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. 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).
OTSSP167 hydrochloride (CAS 1431698-10-0) is a high-purity analytical reference standard with the molecular formula C25H28Cl2N4O2HCl and a molecular weight of 523.88 g/mol.
