Chemical Structure
Description
The occurrence of 5-chloro-1-methyl-pyrazolo[3,4-c]pyridine is closely related to a nitrile group, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
5-chloro-1-methyl-pyrazolo[3,4-c]pyridine (CAS 1521237-92-2) is a high-purity analytical reference standard with the molecular formula C7H14ClN3 and a molecular weight of 175.66 g/mol.
The molecular framework of 5-chloro-1-methyl-pyrazolo[3,4-c]pyridine (C7H14ClN3) is characterized by a nitrile group, chlorine substitution. 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
