4-(4-Bromophenoxy)-6-chloro-1-methyl-1H-pyrazolo[3,4-d]pyrimidine (CAS 5413-98-9), molecular formula C12H8BrClN4O and molecular weight 339.58 g/mol, is a CATO reference standard with documented purity and traceability.
4-(4-Bromophenoxy)-6-chloro-1-methyl-1H-pyrazolo[3,4-d]pyrimidine (C12H8BrClN4O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine/bromine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
