Chemical Structure

1,1,2,2-Tetrabromoethane CAS 79-27-6 chemical structure

Description

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.

1,1,2,2-Tetrabromoethane (CAS 79-27-6) is a high-purity analytical reference standard with the molecular formula C2H2Br4 and a molecular weight of 345.65 g/mol.

Structurally, 1,1,2,2-Tetrabromoethane (C2H2Br4) contains bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 0.0, corresponding to approximately 0 ring(s) or double-bond equivalent(s). With a molecular weight of 345.65 g/mol, it falls into the moderately-high-molecular-weight range. 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.
