4-Bromo-2-(piperidin-1-yl)aniline CAS 402925-36-4

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-Bromo-2-(piperidin-1-yl)aniline.

4-Bromo-2-(piperidin-1-yl)aniline (CAS 402925-36-4) is a high-purity analytical reference standard with the molecular formula C11H15BrN2 and a molecular weight of 255.15 g/mol.

Based on its molecular formula C11H15BrN2, 4-Bromo-2-(piperidin-1-yl)aniline contains a nitrogen-containing heterocyclic scaffold, a nitrile group, bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 255.15 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
