Chemical Structure
Description
Structurally, 1,3-Dimethyl-4,5,6,7-tetrahydro-1H-pyrazolo[3,4-b]pyridin-5-amine dihydrochloride (C8H14N4HCl) contains a nitrile group, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 202.69 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).
1,3-Dimethyl-4,5,6,7-tetrahydro-1H-pyrazolo[3,4-b]pyridin-5-amine dihydrochloride (CAS 2138284-53-2), molecular formula C8H14N4HCl and molecular weight 202.69 g/mol, is a CATO reference standard with documented purity and traceability.
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.
