Description

Compared with other compounds in its class, the molecular weight of 203.24 g/mol gives 4-(2-Aminoethyl)-5-phenyl-1,2-dihydro-3H-pyrazol-3-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

4-(2-Aminoethyl)-5-phenyl-1,2-dihydro-3H-pyrazol-3-one (CAS 878208-75-4), molecular formula C11H13N3O and molecular weight 203.24 g/mol, is a CATO reference standard with documented purity and traceability.

4-(2-Aminoethyl)-5-phenyl-1,2-dihydro-3H-pyrazol-3-one (C11H13N3O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
