5-tert-Butyl-2-iodo-1,3-dimethylbenzene CAS 5122-20-3

Description

Compared with other compounds in its class, the molecular weight of 288.17 g/mol gives 5-tert-Butyl-2-iodo-1,3-dimethylbenzene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

5-tert-Butyl-2-iodo-1,3-dimethylbenzene (CAS 5122-20-3) is a high-purity analytical reference standard with the molecular formula C12H17I and a molecular weight of 288.17 g/mol.

Based on its molecular formula C12H17I, 5-tert-Butyl-2-iodo-1,3-dimethylbenzene contains iodine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 288.17 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.
