Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 211.57 g/mol gives 4-Chloro-3-(trifluoromethoxy)aniline distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 4-Chloro-3-(trifluoromethoxy)aniline (CAS 97608-50-9), a certified reference material (molecular formula C7H5ClF3NO, MW 211.57 g/mol) for analytical method development and quality control.
Structurally, 4-Chloro-3-(trifluoromethoxy)aniline (C7H5ClF3NO) contains an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 211.57 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
