Description
CATO supplies 1,2,3,4,5-Pentachloro-6-trifluoromethyl-benzene (CAS 384-83-8), a certified reference material (molecular formula C7Cl5F3, MW 318.34 g/mol) for analytical method development and quality control.
Based on its molecular formula C7Cl5F3, 1,2,3,4,5-Pentachloro-6-trifluoromethyl-benzene contains fluorine/chlorine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 318.34 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
