4-Bromo-1-(3-ethylcyclohexyl)-1h-pyrazol-3-amine (CAS 1341153-08-9) is a high-purity analytical reference standard with the molecular formula C11H18BrN3 and a molecular weight of 272.18 g/mol.
The molecular framework of 4-Bromo-1-(3-ethylcyclohexyl)-1h-pyrazol-3-amine (C11H18BrN3) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, bromine substitution. 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. 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.
CATO manufactures 4-Bromo-1-(3-ethylcyclohexyl)-1h-pyrazol-3-amine under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
