Chemical Structure
Description
76286-03-8 2-Chloro-4-trifluoromethylbenzoyl chloride MFCD07779332 (C8H3Cl2F3O) contains a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
76286-03-8 2-Chloro-4-trifluoromethylbenzoyl chloride MFCD07779332 (CAS 76286-03-8), molecular formula C8H3Cl2F3O and molecular weight 243.01 g/mol, is a CATO reference standard with documented purity and traceability.
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.
