Chemical Structure

(Z)-1-Iodobut-2-ene CAS 53121-23-6 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.

(Z)-1-Iodobut-2-ene (CAS 53121-23-6), molecular formula C4H7I and molecular weight 182.00 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of (Z)-1-Iodobut-2-ene (C4H7I) is characterized by 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.

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.
