Compared with other compounds in its class, the molecular weight of 296.11 g/mol gives 5-Amino-1-(2,5-dichlorophenyl)-1,5-dihydro-4H-pyrazolo[3,4-d]pyrimidin-4-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 5-Amino-1-(2,5-dichlorophenyl)-1,5-dihydro-4H-pyrazolo[3,4-d]pyrimidin-4-one (CAS 1416342-09-0), a certified reference material (molecular formula C11H7Cl2N5O, MW 296.11 g/mol) for analytical method development and quality control.
5-Amino-1-(2,5-dichlorophenyl)-1,5-dihydro-4H-pyrazolo[3,4-d]pyrimidin-4-one (C11H7Cl2N5O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine 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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
