Chemical Structure
Description
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, 9-Isopropyl-9H-purine is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 162.19 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
9-Isopropyl-9H-purine (CAS 18203-85-5), molecular formula C8H10N4 and molecular weight 162.19 g/mol, is a CATO reference standard with documented purity and traceability.
