1-(2-Bromoethyl)-2,3-dichlorobenzene CAS 958027-82-2

Description

Compared with other compounds in its class, the molecular weight of 253.95 g/mol gives 1-(2-Bromoethyl)-2,3-dichlorobenzene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

1-(2-Bromoethyl)-2,3-dichlorobenzene (CAS 958027-82-2), molecular formula C8H7BrCl2 and molecular weight 253.95 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 1-(2-Bromoethyl)-2,3-dichlorobenzene (C8H7BrCl2) is characterized by chlorine/bromine substitution, an aromatic ring system. 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.

As a certified reference material (CRM), 1-(2-Bromoethyl)-2,3-dichlorobenzene 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.
