1,7-Diiodoheptane CAS 51526-03-5 chemical structure

Description

1,7-Diiodoheptane (CAS 51526-03-5) is a high-purity analytical reference standard with the molecular formula C7H14I2 and a molecular weight of 352.00 g/mol.

Based on its molecular formula C7H14I2, 1,7-Diiodoheptane contains iodine substitution; these features give the compound characteristic molecular-ion distribution patterns in mass spectrometry. The molecular weight of 352.00 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.
