2-Bromo-4-chloro-1-ethylbenzene CAS 1345036-19-2 chemical structure

Description

CATO manufactures 2-Bromo-4-chloro-1-ethylbenzene 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.

2-Bromo-4-chloro-1-ethylbenzene (CAS 1345036-19-2) is a high-purity analytical reference standard with the molecular formula C8H8BrCl and a molecular weight of 219.51 g/mol.

2-Bromo-4-chloro-1-ethylbenzene (C8H8BrCl) contains chlorine/bromine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
