Chemical Structure

5-{1-[3-(trifluoromethyl)phenoxy]ethyl}-1H-pyrazole CAS 321998-98-5 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 5-{1-[3-(trifluoromethyl)phenoxy]ethyl}-1H-pyrazole.

5-{1-[3-(trifluoromethyl)phenoxy]ethyl}-1H-pyrazole (CAS 321998-98-5), molecular formula C12H11F3N2O and molecular weight 256.22 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution, 5-{1-[3-(trifluoromethyl)phenoxy]ethyl}-1H-pyrazole is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 256.22 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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), 5-{1-[3-(trifluoromethyl)phenoxy]ethyl}-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.
