1,3-Bis(4-chlorophenyl)-1H-pyrazol-5-amine CAS 618092-72-1

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1,3-Bis(4-chlorophenyl)-1H-pyrazol-5-amine.

1,3-Bis(4-chlorophenyl)-1H-pyrazol-5-amine (CAS 618092-72-1) is a high-purity analytical reference standard with the molecular formula C15H11Cl2N3 and a molecular weight of 304.17 g/mol.

Based on its molecular formula C15H11Cl2N3, 1,3-Bis(4-chlorophenyl)-1H-pyrazol-5-amine contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 304.17 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.

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.
