Chemical Structure
Description
The occurrence of 1,2-Dibromoethane- is closely related to bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
1,2-Dibromoethane- (CAS 33458-49-0), molecular formula [13C]2H4Br2 and molecular weight 189.85 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1,2-Dibromoethane- ([13C]2H4Br2) 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.
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 1,2-Dibromoethane- 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.
