METHYL 2-IODOBENZENESULFONATE CAS 850078-95-4 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including METHYL 2-IODOBENZENESULFONATE.

METHYL 2-IODOBENZENESULFONATE (CAS 850078-95-4) is a high-purity analytical reference standard with the molecular formula C7H7IO3S and a molecular weight of 298.10 g/mol.

The molecular framework of METHYL 2-IODOBENZENESULFONATE (C7H7IO3S) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, 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. 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.

CATO manufactures METHYL 2-IODOBENZENESULFONATE under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
