Chemical Structure
Description
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine substitution, 1-(3-Fluorophenyl)pyrazole is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 162.16 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.
1-(3-Fluorophenyl)pyrazole (CAS 37649-86-8) is a high-purity analytical reference standard with the molecular formula C9H7FN2 and a molecular weight of 162.16 g/mol.
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 1-(3-Fluorophenyl)pyrazole 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.
