Chemical Structure
Description
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.
5-Chloro-1-iodo-2-methyl-3-nitrobenzene (CAS 294190-16-2) is a high-purity analytical reference standard with the molecular formula C7H5ClINO2 and a molecular weight of 297.48 g/mol.
Based on its molecular formula C7H5ClINO2, 5-Chloro-1-iodo-2-methyl-3-nitrobenzene contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine/iodine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 297.48 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).
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.
