Chemical Structure
Description
Structurally, 5-(2-Methoxyphenoxy)-1-phenyl-1H-pyrazolo[3,4-b]pyrazine (C18H14N4O2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 14.0, corresponding to approximately 14 ring(s) or double-bond equivalent(s). With a molecular weight of 318.33 g/mol, it falls into the moderately-high-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).
5-(2-Methoxyphenoxy)-1-phenyl-1H-pyrazolo[3,4-b]pyrazine (CAS 87595-07-1) is a high-purity analytical reference standard with the molecular formula C18H14N4O2 and a molecular weight of 318.33 g/mol.
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.
