Chemical Structure
Description
3-Amino-5-(2-fluoro-5-methylphenyl)pyrazole (CAS 97052-86-3) is a high-purity analytical reference standard with the molecular formula C10H10FN3 and a molecular weight of 191.20 g/mol.
The molecular framework of 3-Amino-5-(2-fluoro-5-methylphenyl)pyrazole (C10H10FN3) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine 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. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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 3-Amino-5-(2-fluoro-5-methylphenyl)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.
