Chemical Structure
Description
(R)-7-(but-2-yn-1-yl)-3-methyl-8-(3-(5-methyl-1,3-dioxoisoindolin-2-yl)piperidin-1-yl)-1-((4-methylquinazolin-2-yl)methyl)-3,7-dihydro-1H-purine-2,6-dione (CAS 1573118-33-8), molecular formula C34H32N8O4 and molecular weight 616.67 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (R)-7-(but-2-yn-1-yl)-3-methyl-8-(3-(5-methyl-1,3-dioxoisoindolin-2-yl)piperidin-1-yl)-1-((4-methylquinazolin-2-yl)methyl)-3,7-dihydro-1H-purine-2,6-dione (C34H32N8O4) is characterized by a nitrogen-containing heterocyclic scaffold, an amide 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
