Chemical Structure
Description
4-Bromo-5-(butoxymethyl)-1-(3,3,3-trifluoropropyl)-1H-pyrazole (CAS 1856045-54-9) is a high-purity analytical reference standard with the molecular formula C11H16BrF3N2O and a molecular weight of 329.16 g/mol.
The molecular framework of 4-Bromo-5-(butoxymethyl)-1-(3,3,3-trifluoropropyl)-1H-pyrazole (C11H16BrF3N2O) is characterized by an amide group, a hydroxyl group, an ether linkage, fluorine/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. 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 4-Bromo-5-(butoxymethyl)-1-(3,3,3-trifluoropropyl)-1H-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.
