Chemical Structure
Description
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.
(S)-2-(1-(3-ethyl-7-((pyridin-3-ylmethyl)amino)pyrazolo[1,5-a]pyrimidin-5-yl)piperidin-2-yl)ethanol (CAS 779353-02-5) is a high-purity analytical reference standard with the molecular formula C21H28N6O and a molecular weight of 380.49 g/mol.
The molecular framework of (S)-2-(1-(3-ethyl-7-((pyridin-3-ylmethyl)amino)pyrazolo[1,5-a]pyrimidin-5-yl)piperidin-2-yl)ethanol (C21H28N6O) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
