Chemical Structure
Description
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.
2-Fluoro-5-(trifluoromethyl)benzoyl chloride 2-fluoro-5-trifluoromethylbenzoyl chloride 2-fluoro-5-trifluoromethylbenzoylchloride 2-fluoro-5-(trifluoromethyl)benzoylchloride 207981-46-2 (CAS 207981-46-2), molecular formula C8H3ClF4O and molecular weight 226.56 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system, 2-Fluoro-5-(trifluoromethyl)benzoyl chloride 2-fluoro-5-trifluoromethylbenzoyl chloride 2-fluoro-5-trifluoromethylbenzoylchloride 2-fluoro-5-(trifluoromethyl)benzoylchloride 207981-46-2 is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 226.56 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
