Chemical Structure
Description
6-(Methylsulfanyl)-1-phenyl-4-(2,4,5-trichlorophenoxy)-1H-pyrazolo[3,4-d]pyrimidine (CAS 341968-32-9) is a high-purity analytical reference standard with the molecular formula C18H11Cl3N4OS and a molecular weight of 437.73 g/mol.
The molecular framework of 6-(Methylsulfanyl)-1-phenyl-4-(2,4,5-trichlorophenoxy)-1H-pyrazolo[3,4-d]pyrimidine (C18H11Cl3N4OS) is characterized by a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution. 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
