Chemical Structure

3-Iodobut-3-enoic acid CAS 157104-38-6 chemical structure

Description

CATO supplies 3-Iodobut-3-enoic acid (CAS 157104-38-6), a certified reference material (molecular formula C4H5IO2, MW 211.99 g/mol) for analytical method development and quality control.

The molecular framework of 3-Iodobut-3-enoic acid (C4H5IO2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, iodine substitution. 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 3-Iodobut-3-enoic acid 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.
