Chemical Structure
Description
4-Bromo-3-(butoxymethyl)-1-butyl-1H-pyrazole (CAS 1856085-24-9), molecular formula C12H21BrN2O and molecular weight 289.21 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4-Bromo-3-(butoxymethyl)-1-butyl-1H-pyrazole (C12H21BrN2O) 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 4-Bromo-3-(butoxymethyl)-1-butyl-1H-pyrazole meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
