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.
tert-Butyl 3-(7-aminopyrazolo[1,5-a]pyrimidin-5-yl)piperidine-1-carboxylate (CAS 930595-69-0) is a high-purity analytical reference standard with the molecular formula C16H23N5O2 and a molecular weight of 317.39 g/mol.
tert-Butyl 3-(7-aminopyrazolo[1,5-a]pyrimidin-5-yl)piperidine-1-carboxylate (C16H23N5O2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
