4-Iodo-2-methyl-1-butene CAS 53750-52-0

Description

The occurrence of 4-Iodo-2-methyl-1-butene is closely related to iodine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

4-Iodo-2-methyl-1-butene (CAS 53750-52-0), molecular formula C5H9I and molecular weight 196.03 g/mol, is a CATO reference standard with documented purity and traceability.

4-Iodo-2-methyl-1-butene (C5H9I) contains iodine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
