Chemical Structure
Description
2-Chloro-1-iodo-3-(trifluoromethyl)benzene (CAS 1369918-95-5), molecular formula C7H3ClF3I and molecular weight 306.45 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 2-Chloro-1-iodo-3-(trifluoromethyl)benzene (C7H3ClF3I) contains fluorine/chlorine/iodine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 306.45 g/mol, it falls into the moderately-high-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
