Description

Compared with other compounds in its class, the molecular weight of 243.34 g/mol gives 4-Nitro-1-((2-(trimethylsilyl)ethoxy)methyl)-1H-pyrazole distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

4-Nitro-1-((2-(trimethylsilyl)ethoxy)methyl)-1H-pyrazole (CAS 1260160-79-9), molecular formula C9H17N3O3Si and molecular weight 243.34 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 4-Nitro-1-((2-(trimethylsilyl)ethoxy)methyl)-1H-pyrazole (C9H17N3O3Si) is characterized by an amino-acid-derived structure, 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. 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).

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.

As a certified reference material (CRM), 4-Nitro-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.
