4-Amino-5-cyclopropyl-1-methyl-2-phenyl-2,3-dihydro-1h-pyrazol-3-one CAS 856847-31-9 chemical structure

Description

The occurrence of 4-Amino-5-cyclopropyl-1-methyl-2-phenyl-2,3-dihydro-1h-pyrazol-3-one is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

4-Amino-5-cyclopropyl-1-methyl-2-phenyl-2,3-dihydro-1h-pyrazol-3-one (CAS 856847-31-9) is a high-purity analytical reference standard with the molecular formula C13H15N3O and a molecular weight of 229.28 g/mol.

Based on its molecular formula C13H15N3O, 4-Amino-5-cyclopropyl-1-methyl-2-phenyl-2,3-dihydro-1h-pyrazol-3-one contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 229.28 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.

As a certified reference material (CRM), 4-Amino-5-cyclopropyl-1-methyl-2-phenyl-2,3-dihydro-1h-pyrazol-3-one meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
