Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 286.56 g/mol gives 1-[(4-bromo-2-chlorophenyl)methyl]-1H-pyrazol-4-amine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
1-[(4-bromo-2-chlorophenyl)methyl]-1H-pyrazol-4-amine (CAS 1602185-22-7), molecular formula C10H9BrClN3 and molecular weight 286.56 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1-[(4-bromo-2-chlorophenyl)methyl]-1H-pyrazol-4-amine (C10H9BrClN3) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine/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 1-[(4-bromo-2-chlorophenyl)methyl]-1H-pyrazol-4-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.
