The occurrence of 6-chloro-2,3-dimethyl-2H-pyrazolo[3,4-d]pyrimidine is closely related to a nitrile group, chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
6-chloro-2,3-dimethyl-2H-pyrazolo[3,4-d]pyrimidine (CAS 1935641-38-5) is a high-purity analytical reference standard with the molecular formula C7H7ClN4 and a molecular weight of 182.61 g/mol.
The molecular framework of 6-chloro-2,3-dimethyl-2H-pyrazolo[3,4-d]pyrimidine (C7H7ClN4) is characterized by a nitrile group, chlorine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
