1-(4,6-Dimethyl-1H-pyrazolo[3,4-b]pyridin-3-yl)-3-phenylthiourea (CAS 131944-98-4), molecular formula C15H15N5S and molecular weight 297.38 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 1-(4,6-Dimethyl-1H-pyrazolo[3,4-b]pyridin-3-yl)-3-phenylthiourea (C15H15N5S) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality. The molecule exhibits a degree of unsaturation (DBE) of 11.0, corresponding to approximately 11 ring(s) or double-bond equivalent(s). With a molecular weight of 297.38 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).
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.
