Chemical Structure
Description
4-bromo-1-phenyl-1H-pyrazol-5-amine (CAS 5900-00-5) is a high-purity analytical reference standard with the molecular formula C9H8BrN3 and a molecular weight of 238.08 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, bromine substitution, 4-bromo-1-phenyl-1H-pyrazol-5-amine is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 238.08 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures 4-bromo-1-phenyl-1H-pyrazol-5-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.
