Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 249.44 g/mol gives 1,2,5-Trichloro-3-(trifluoromethyl)benzene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
1,2,5-Trichloro-3-(trifluoromethyl)benzene (CAS 61841-46-1), molecular formula C7H2Cl3F3 and molecular weight 249.44 g/mol, is a CATO reference standard with documented purity and traceability.
1,2,5-Trichloro-3-(trifluoromethyl)benzene (C7H2Cl3F3) contains 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
