6-Chloro-1-isobutyl-1H-pyrazolo[3,4-d]pyrimidin-4(5H)-one CAS 1415093-41-2

Description

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.

6-Chloro-1-isobutyl-1H-pyrazolo[3,4-d]pyrimidin-4(5H)-one (CAS 1415093-41-2) is a high-purity analytical reference standard with the molecular formula C9H11ClN4O and a molecular weight of 226.66 g/mol.

Structurally, 6-Chloro-1-isobutyl-1H-pyrazolo[3,4-d]pyrimidin-4(5H)-one (C9H11ClN4O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 226.66 g/mol, it falls into the medium-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
