3-Isopropyl-1-(4-methoxyphenyl)-1H-pyrazol-5(4H)-one CAS 1049151-87-2

Description

Compared with other compounds in its class, the molecular weight of 232.28 g/mol gives 3-Isopropyl-1-(4-methoxyphenyl)-1H-pyrazol-5(4H)-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

3-Isopropyl-1-(4-methoxyphenyl)-1H-pyrazol-5(4H)-one (CAS 1049151-87-2), molecular formula C13H16N2O2 and molecular weight 232.28 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 3-Isopropyl-1-(4-methoxyphenyl)-1H-pyrazol-5(4H)-one (C13H16N2O2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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), 3-Isopropyl-1-(4-methoxyphenyl)-1H-pyrazol-5(4H)-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.
