3,4-Dibutyl-2-iodothiophene CAS 565186-12-1

Description

Compared with other compounds in its class, the molecular weight of 322.25 g/mol gives 3,4-Dibutyl-2-iodothiophene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

3,4-Dibutyl-2-iodothiophene (CAS 565186-12-1) is a high-purity analytical reference standard with the molecular formula C12H19IS and a molecular weight of 322.25 g/mol.

The molecular framework of 3,4-Dibutyl-2-iodothiophene (C12H19IS) is characterized by sulfur-containing functionality, iodine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), 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.

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.
