Chemical Structure
Description
The occurrence of 4-chloro-1h-pyrazolo[3,4-b]pyridine-3-carbonitrile 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.
CATO supplies 4-chloro-1h-pyrazolo[3,4-b]pyridine-3-carbonitrile (CAS 1936189-92-2), a certified reference material (molecular formula C7H11ClN4, MW 186.64 g/mol) for analytical method development and quality control.
Structurally, 4-chloro-1h-pyrazolo[3,4-b]pyridine-3-carbonitrile (C7H11ClN4) contains a nitrile group, chlorine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 186.64 g/mol, it falls into the medium-molecular-weight range. 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.
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.
