Chemical Structure
Description
Structurally, 3-(2-Methoxyphenyl)-5-methyl-7-(4-phenylpiperazin-1-yl)pyrazolo[1,5-a]pyrimidine (C24H25N5O) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 15.0, corresponding to approximately 15 ring(s) or double-bond equivalent(s). With a molecular weight of 399.49 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).
3-(2-Methoxyphenyl)-5-methyl-7-(4-phenylpiperazin-1-yl)pyrazolo[1,5-a]pyrimidine (CAS 879584-20-0) is a high-purity analytical reference standard with the molecular formula C24H25N5O and a molecular weight of 399.49 g/mol.
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.
