3,4-Dimethyl-1-phenyl-1H-pyrazolo[3,4-b]pyridin-6-ol CAS 17321-44-7

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3,4-Dimethyl-1-phenyl-1H-pyrazolo[3,4-b]pyridin-6-ol.

3,4-Dimethyl-1-phenyl-1H-pyrazolo[3,4-b]pyridin-6-ol (CAS 17321-44-7) is a high-purity analytical reference standard with the molecular formula C14H13N3O and a molecular weight of 239.27 g/mol.

Structurally, 3,4-Dimethyl-1-phenyl-1H-pyrazolo[3,4-b]pyridin-6-ol (C14H13N3O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 239.27 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
