Chemical Structure
Description
As a certified reference material (CRM), 4-Bromo-1-(tert-butyldimethylsilyl)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.
CATO supplies 4-Bromo-1-(tert-butyldimethylsilyl)pyrazole (CAS 130874-28-1), a certified reference material (molecular formula C9H17BrN2Si, MW 261.23 g/mol) for analytical method development and quality control.
The molecular framework of 4-Bromo-1-(tert-butyldimethylsilyl)pyrazole (C9H17BrN2Si) is characterized by a nitrile group, bromine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
