Chemical Structure
Description
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.
2-(4-(5,6-Dimethyl-3-phenylpyrazolo[1,5-a]pyrimidin-7-yl)piperazin-1-yl)ethan-1-ol (CAS 890617-97-7) is a high-purity analytical reference standard with the molecular formula C20H25N5O and a molecular weight of 351.45 g/mol.
Based on its molecular formula C20H25N5O, 2-(4-(5,6-Dimethyl-3-phenylpyrazolo[1,5-a]pyrimidin-7-yl)piperazin-1-yl)ethan-1-ol contains a steroid core, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 351.45 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
