N-(1-isopropyl-1H-pyrazol-5-yl)-N’-phenylurea CAS 1955564-45-0

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including N-(1-isopropyl-1H-pyrazol-5-yl)-N’-phenylurea.

N-(1-isopropyl-1H-pyrazol-5-yl)-N’-phenylurea (CAS 1955564-45-0) is a high-purity analytical reference standard with the molecular formula C13H16N4O and a molecular weight of 244.29 g/mol.

Based on its molecular formula C13H16N4O, N-(1-isopropyl-1H-pyrazol-5-yl)-N’-phenylurea 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 244.29 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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), N-(1-isopropyl-1H-pyrazol-5-yl)-N’-phenylurea 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.
