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-Iodo-1,3-dimethyl-5-(trifluoromethyl)benzene (CAS 875550-67-7), molecular formula C9H8F3I and molecular weight 300.06 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-Iodo-1,3-dimethyl-5-(trifluoromethyl)benzene (C9H8F3I) is characterized by fluorine/iodine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
