Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
1-(Piperazin-1-yl)-3-(1H-pyrazol-1-yl)propan-1-one hydrochloride (CAS 1591597-34-0), molecular formula C10H16N4OHCl and molecular weight 244.72 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1-(Piperazin-1-yl)-3-(1H-pyrazol-1-yl)propan-1-one hydrochloride (C10H16N4OHCl) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. 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. 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).
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.
