3-(5-Chlorothiophen-2-yl)-1-phenyl-1h-pyrazol-4-amine CAS 1015517-31-3

Description

3-(5-Chlorothiophen-2-yl)-1-phenyl-1h-pyrazol-4-amine (CAS 1015517-31-3) is a high-purity analytical reference standard with the molecular formula C13H10ClN3S and a molecular weight of 275.76 g/mol.

Based on its molecular formula C13H10ClN3S, 3-(5-Chlorothiophen-2-yl)-1-phenyl-1h-pyrazol-4-amine contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 275.76 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.

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.
