Chemical Structure

4-((Tert-butyldimethylsilyl)oxy)-1H-pyrazole CAS 226989-29-3 chemical structure

Description

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 supplies 4-((Tert-butyldimethylsilyl)oxy)-1H-pyrazole (CAS 226989-29-3), a certified reference material (molecular formula C9H18N2OSi, MW 198.34 g/mol) for analytical method development and quality control.

The molecular framework of 4-((Tert-butyldimethylsilyl)oxy)-1H-pyrazole (C9H18N2OSi) is characterized by an amide group, a hydroxyl group, an ether linkage. 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.

As a certified reference material (CRM), 4-((Tert-butyldimethylsilyl)oxy)-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.
