4-Amino-5-fluoro-2-(trifluoromethoxy)benzonitrile CAS 1803754-22-4 chemical structure

Description

The occurrence of 4-Amino-5-fluoro-2-(trifluoromethoxy)benzonitrile is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

4-Amino-5-fluoro-2-(trifluoromethoxy)benzonitrile (CAS 1803754-22-4), molecular formula C8H4F4N2O and molecular weight 220.12 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 4-Amino-5-fluoro-2-(trifluoromethoxy)benzonitrile (C8H4F4N2O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 220.12 g/mol, it falls into the medium-molecular-weight range. 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-Amino-5-fluoro-2-(trifluoromethoxy)benzonitrile 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.
