Chemical Structure
Description
The occurrence of 5-Methyl-2-phenyl-4,5,6,7-tetrahydro-2H-pyrazolo[3,4-b]pyridin-3-ol is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 5-Methyl-2-phenyl-4,5,6,7-tetrahydro-2H-pyrazolo[3,4-b]pyridin-3-ol (CAS 1707371-91-2), a certified reference material (molecular formula C13H15N3O, MW 229.28 g/mol) for analytical method development and quality control.
Structurally, 5-Methyl-2-phenyl-4,5,6,7-tetrahydro-2H-pyrazolo[3,4-b]pyridin-3-ol (C13H15N3O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 229.28 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.
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.
As a certified reference material (CRM), 5-Methyl-2-phenyl-4,5,6,7-tetrahydro-2H-pyrazolo[3,4-b]pyridin-3-ol meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
