1-(3-bromophenyl)-4-chloro-1H-pyrazolo[3,4-d]pyrimidine CAS 650628-17-4

Description

1-(3-bromophenyl)-4-chloro-1H-pyrazolo[3,4-d]pyrimidine (C11H6BrClN4) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine/bromine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

1-(3-bromophenyl)-4-chloro-1H-pyrazolo[3,4-d]pyrimidine (CAS 650628-17-4) is a high-purity analytical reference standard with the molecular formula C11H6BrClN4 and a molecular weight of 309.55 g/mol.

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.
