Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 173.64 g/mol gives 5-Pyrrolidin-2-yl-1H-pyrazole dihydrochloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
5-Pyrrolidin-2-yl-1H-pyrazole dihydrochloride (CAS 1361114-72-8), molecular formula C7H11N3HCl and molecular weight 173.64 g/mol, is a CATO reference standard with documented purity and traceability.
5-Pyrrolidin-2-yl-1H-pyrazole dihydrochloride (C7H11N3HCl) contains a nitrile group, chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
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.
