4-Bromo-1-butyl-3-(isopropoxymethyl)-1H-pyrazole CAS 1856085-86-3

Description

Compared with other compounds in its class, the molecular weight of 275.19 g/mol gives 4-Bromo-1-butyl-3-(isopropoxymethyl)-1H-pyrazole distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 4-Bromo-1-butyl-3-(isopropoxymethyl)-1H-pyrazole (CAS 1856085-86-3), a certified reference material (molecular formula C11H19BrN2O, MW 275.19 g/mol) for analytical method development and quality control.

The molecular framework of 4-Bromo-1-butyl-3-(isopropoxymethyl)-1H-pyrazole (C11H19BrN2O) is characterized by an amide group, a hydroxyl group, an ether linkage, 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.

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 4-Bromo-1-butyl-3-(isopropoxymethyl)-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.
