4-Bromo-1-((2-(trimethylsilyl)ethoxy)methyl)-1h-pyrazole CAS 133560-58-4 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-Bromo-1-((2-(trimethylsilyl)ethoxy)methyl)-1h-pyrazole.

4-Bromo-1-((2-(trimethylsilyl)ethoxy)methyl)-1h-pyrazole (CAS 133560-58-4) is a high-purity analytical reference standard with the molecular formula C9H17BrN2OSi and a molecular weight of 277.23 g/mol.

The molecular framework of 4-Bromo-1-((2-(trimethylsilyl)ethoxy)methyl)-1h-pyrazole (C9H17BrN2OSi) is characterized by an amide group, a hydroxyl group, an ether linkage, 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.

As a certified reference material (CRM), 4-Bromo-1-((2-(trimethylsilyl)ethoxy)methyl)-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.
