Chemical Structure

3-(Difluoromethoxy)-1H-pyrazole CAS 1799541-57-3 chemical structure

Description

3-(Difluoromethoxy)-1H-pyrazole (CAS 1799541-57-3), molecular formula C4H4F2N2O and molecular weight 134.08 g/mol, is a CATO reference standard with documented purity and traceability.

3-(Difluoromethoxy)-1H-pyrazole (C4H4F2N2O) contains an amide group, a hydroxyl group, an ether linkage, fluorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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), 3-(Difluoromethoxy)-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.
