Chemical Structure

1,1-Dibromoethane (contains stabilizer ) CAS 557-91-5 chemical structure

Description

The molecular framework of 1,1-Dibromoethane (contains stabilizer ) (C2H4Br2) 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-Dibromoethane (contains stabilizer ) (CAS 557-91-5) is a high-purity analytical reference standard with the molecular formula C2H4Br2 and a molecular weight of 187.86 g/mol.

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.

CATO manufactures 1,1-Dibromoethane (contains stabilizer ) under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
