Chemical Structure

4-Phenoxy-2,2,2-trifluoroacetophenone CAS 70783-32-3 chemical structure

Description

The occurrence of 4-Phenoxy-2,2,2-trifluoroacetophenone is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 4-Phenoxy-2,2,2-trifluoroacetophenone (CAS 70783-32-3), a certified reference material (molecular formula C14H9F3O2, MW 266.22 g/mol) for analytical method development and quality control.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, a polycyclic aromatic system, 4-Phenoxy-2,2,2-trifluoroacetophenone is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 266.22 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
