The occurrence of Methyl 2-[(4-chlorobenzenesulfonyl)oxy]-5-iodobenzoate is closely related to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine/iodine substitution, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies Methyl 2-[(4-chlorobenzenesulfonyl)oxy]-5-iodobenzoate (CAS 297150-23-3), a certified reference material (molecular formula C14H10ClIO5S, MW 452.65 g/mol) for analytical method development and quality control.
Based on its molecular formula C14H10ClIO5S, Methyl 2-[(4-chlorobenzenesulfonyl)oxy]-5-iodobenzoate contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine/iodine substitution, a polycyclic aromatic system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 452.65 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
