Chemical Structure

1,1,2,2-TETRABROMOETHANE CAS 25167-20-8 chemical structure

Description

The molecular framework of 1,1,2,2-TETRABROMOETHANE (C2H2Br4) is characterized by bromine substitution. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, 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.

1,1,2,2-TETRABROMOETHANE (CAS 25167-20-8), molecular formula C2H2Br4 and molecular weight 345.65 g/mol, is a CATO reference standard with documented purity and traceability.

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.

As a certified reference material (CRM), 1,1,2,2-TETRABROMOETHANE meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
