Chemical Structure
Description
CATO supplies 1-Chloro-2-iodo-3-(trifluoromethyl)benzene (CAS 203626-41-9), a certified reference material (molecular formula C7H3ClF3I, MW 306.45 g/mol) for analytical method development and quality control.
1-Chloro-2-iodo-3-(trifluoromethyl)benzene (C7H3ClF3I) contains fluorine/chlorine/iodine 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).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
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.
